Changed trunk directory name

Emmanuel Bertin <bertin@iap.fr> :	SExtractor code and FITS library

V2.5 (2006-07-14)

COOSYS epoch and system are not set to the proper values in ASCII_VOTABLE

catalogs.

Unexpected crashes are experienced when working with extremely large images

(10+Gpixels). This was not the case with earlier versions (ca. 1999).

V2.3 (2002-12-17)

ASSOC options do not work properly with MEF images (this is not really a bug).

                         Version 2, June 1991

     Copyright (C) 1989, 1991 Free Software Foundation, Inc.

     59 Temple Place - Suite 330, Boston, MA  02111-1307, USA

     Everyone is permitted to copy and distribute verbatim copies

     of this license document, but changing it is not allowed.

Preamble

========

The licenses for most software are designed to take away your freedom

to share and change it.  By contrast, the GNU General Public License is

intended to guarantee your freedom to share and change free

software--to make sure the software is free for all its users.  This

General Public License applies to most of the Free Software

Foundation's software and to any other program whose authors commit to

using it.  (Some other Free Software Foundation software is covered by

the GNU Library General Public License instead.)  You can apply it to

your programs, too.

When we speak of free software, we are referring to freedom, not price.

Our General Public Licenses are designed to make sure that you have

the freedom to distribute copies of free software (and charge for this

service if you wish), that you receive source code or can get it if you

want it, that you can change the software or use pieces of it in new

free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone

to deny you these rights or to ask you to surrender the rights.  These

restrictions translate to certain responsibilities for you if you

distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis

or for a fee, you must give the recipients all the rights that you

have.  You must make sure that they, too, receive or can get the source

code.  And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and

(2) offer you this license which gives you legal permission to copy,

distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain

that everyone understands that there is no warranty for this free

software.  If the software is modified by someone else and passed on, we

want its recipients to know that what they have is not the original, so

that any problems introduced by others will not reflect on the original

authors' reputations.

Finally, any free program is threatened constantly by software patents.

We wish to avoid the danger that redistributors of a free program will

individually obtain patent licenses, in effect making the program

proprietary.  To prevent this, we have made it clear that any patent

must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and

modification follow.

                      GNU GENERAL PUBLIC LICENSE

    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  0. This License applies to any program or other work which contains a

     notice placed by the copyright holder saying it may be distributed

     under the terms of this General Public License.  The "Program",

     below, refers to any such program or work, and a "work based on

     the Program" means either the Program or any derivative work under

     copyright law: that is to say, a work containing the Program or a

     portion of it, either verbatim or with modifications and/or

     translated into another language.  (Hereinafter, translation is

     included without limitation in the term "modification".)  Each

     licensee is addressed as "you".

     Activities other than copying, distribution and modification are

     not covered by this License; they are outside its scope.  The act

     of running the Program is not restricted, and the output from the

     Program is covered only if its contents constitute a work based on

     the Program (independent of having been made by running the

     Program).  Whether that is true depends on what the Program does.

  1. You may copy and distribute verbatim copies of the Program's

     source code as you receive it, in any medium, provided that you

     conspicuously and appropriately publish on each copy an appropriate

     copyright notice and disclaimer of warranty; keep intact all the

     notices that refer to this License and to the absence of any

     warranty; and give any other recipients of the Program a copy of

     this License along with the Program.

     You may charge a fee for the physical act of transferring a copy,

     and you may at your option offer warranty protection in exchange

     for a fee.

  2. You may modify your copy or copies of the Program or any portion

     of it, thus forming a work based on the Program, and copy and

     distribute such modifications or work under the terms of Section 1

     above, provided that you also meet all of these conditions:

       a. You must cause the modified files to carry prominent notices

          stating that you changed the files and the date of any change.

       b. You must cause any work that you distribute or publish, that

          in whole or in part contains or is derived from the Program

          or any part thereof, to be licensed as a whole at no charge

          to all third parties under the terms of this License.

       c. If the modified program normally reads commands interactively

          when run, you must cause it, when started running for such

          interactive use in the most ordinary way, to print or display

          an announcement including an appropriate copyright notice and

          a notice that there is no warranty (or else, saying that you

          provide a warranty) and that users may redistribute the

          program under these conditions, and telling the user how to

          view a copy of this License.  (Exception: if the Program

          itself is interactive but does not normally print such an

          announcement, your work based on the Program is not required

          to print an announcement.)

     These requirements apply to the modified work as a whole.  If

     identifiable sections of that work are not derived from the

     Program, and can be reasonably considered independent and separate

     works in themselves, then this License, and its terms, do not

     apply to those sections when you distribute them as separate

     works.  But when you distribute the same sections as part of a

     whole which is a work based on the Program, the distribution of

     the whole must be on the terms of this License, whose permissions

     for other licensees extend to the entire whole, and thus to each

     and every part regardless of who wrote it.

     Thus, it is not the intent of this section to claim rights or

     contest your rights to work written entirely by you; rather, the

     intent is to exercise the right to control the distribution of

     derivative or collective works based on the Program.

     In addition, mere aggregation of another work not based on the

     Program with the Program (or with a work based on the Program) on

     a volume of a storage or distribution medium does not bring the

     other work under the scope of this License.

  3. You may copy and distribute the Program (or a work based on it,

     under Section 2) in object code or executable form under the terms

     of Sections 1 and 2 above provided that you also do one of the

     following:

       a. Accompany it with the complete corresponding machine-readable

          source code, which must be distributed under the terms of

          Sections 1 and 2 above on a medium customarily used for

          software interchange; or,

       b. Accompany it with a written offer, valid for at least three

          years, to give any third party, for a charge no more than your

          cost of physically performing source distribution, a complete

          machine-readable copy of the corresponding source code, to be

          distributed under the terms of Sections 1 and 2 above on a

          medium customarily used for software interchange; or,

       c. Accompany it with the information you received as to the offer

          to distribute corresponding source code.  (This alternative is

          allowed only for noncommercial distribution and only if you

          received the program in object code or executable form with

          such an offer, in accord with Subsection b above.)

     The source code for a work means the preferred form of the work for

     making modifications to it.  For an executable work, complete

     source code means all the source code for all modules it contains,

     plus any associated interface definition files, plus the scripts

     used to control compilation and installation of the executable.

     However, as a special exception, the source code distributed need

     not include anything that is normally distributed (in either

     source or binary form) with the major components (compiler,

     kernel, and so on) of the operating system on which the executable

     runs, unless that component itself accompanies the executable.

     If distribution of executable or object code is made by offering

     access to copy from a designated place, then offering equivalent

     access to copy the source code from the same place counts as

     distribution of the source code, even though third parties are not

     compelled to copy the source along with the object code.

  4. You may not copy, modify, sublicense, or distribute the Program

     except as expressly provided under this License.  Any attempt

     otherwise to copy, modify, sublicense or distribute the Program is

     void, and will automatically terminate your rights under this

     License.  However, parties who have received copies, or rights,

     from you under this License will not have their licenses

     terminated so long as such parties remain in full compliance.

  5. You are not required to accept this License, since you have not

     signed it.  However, nothing else grants you permission to modify

     or distribute the Program or its derivative works.  These actions

     are prohibited by law if you do not accept this License.

     Therefore, by modifying or distributing the Program (or any work

     based on the Program), you indicate your acceptance of this

     License to do so, and all its terms and conditions for copying,

     distributing or modifying the Program or works based on it.

  6. Each time you redistribute the Program (or any work based on the

     Program), the recipient automatically receives a license from the

     original licensor to copy, distribute or modify the Program

     subject to these terms and conditions.  You may not impose any

     further restrictions on the recipients' exercise of the rights

     granted herein.  You are not responsible for enforcing compliance

     by third parties to this License.

  7. If, as a consequence of a court judgment or allegation of patent

     infringement or for any other reason (not limited to patent

     issues), conditions are imposed on you (whether by court order,

     agreement or otherwise) that contradict the conditions of this

     License, they do not excuse you from the conditions of this

     License.  If you cannot distribute so as to satisfy simultaneously

     your obligations under this License and any other pertinent

     obligations, then as a consequence you may not distribute the

     Program at all.  For example, if a patent license would not permit

     royalty-free redistribution of the Program by all those who

     receive copies directly or indirectly through you, then the only

     way you could satisfy both it and this License would be to refrain

     entirely from distribution of the Program.

     If any portion of this section is held invalid or unenforceable

     under any particular circumstance, the balance of the section is

     intended to apply and the section as a whole is intended to apply

     in other circumstances.

     It is not the purpose of this section to induce you to infringe any

     patents or other property right claims or to contest validity of

     any such claims; this section has the sole purpose of protecting

     the integrity of the free software distribution system, which is

     implemented by public license practices.  Many people have made

     generous contributions to the wide range of software distributed

     through that system in reliance on consistent application of that

     system; it is up to the author/donor to decide if he or she is

     willing to distribute software through any other system and a

     licensee cannot impose that choice.

     This section is intended to make thoroughly clear what is believed

     to be a consequence of the rest of this License.

  8. If the distribution and/or use of the Program is restricted in

     certain countries either by patents or by copyrighted interfaces,

     the original copyright holder who places the Program under this

     License may add an explicit geographical distribution limitation

     excluding those countries, so that distribution is permitted only

     in or among countries not thus excluded.  In such case, this

     License incorporates the limitation as if written in the body of

     this License.

  9. The Free Software Foundation may publish revised and/or new

     versions of the General Public License from time to time.  Such

     new versions will be similar in spirit to the present version, but

     may differ in detail to address new problems or concerns.

     Each version is given a distinguishing version number.  If the

     Program specifies a version number of this License which applies

     to it and "any later version", you have the option of following

     the terms and conditions either of that version or of any later

     version published by the Free Software Foundation.  If the Program

     does not specify a version number of this License, you may choose

     any version ever published by the Free Software Foundation.

 10. If you wish to incorporate parts of the Program into other free

     programs whose distribution conditions are different, write to the

     author to ask for permission.  For software which is copyrighted

     by the Free Software Foundation, write to the Free Software

     Foundation; we sometimes make exceptions for this.  Our decision

     will be guided by the two goals of preserving the free status of

     all derivatives of our free software and of promoting the sharing

     and reuse of software generally.

                                NO WARRANTY

 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO

     WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE

     LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT

     HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT

     WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT

     NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND

     FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE

     QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE

     PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY

     SERVICING, REPAIR OR CORRECTION.

 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN

     WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY

     MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE

     LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,

     INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR

     INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF

     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU

     OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY

     OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN

     ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

                      END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

=============================================

If you develop a new program, and you want it to be of the greatest

possible use to the public, the best way to achieve this is to make it

free software which everyone can redistribute and change under these

terms.

To do so, attach the following notices to the program.  It is safest to

attach them to the start of each source file to most effectively convey

the exclusion of warranty; and each file should have at least the

"copyright" line and a pointer to where the full notice is found.

     ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES.

     Copyright (C) YYYY  NAME OF AUTHOR

     This program is free software; you can redistribute it and/or modify

     it under the terms of the GNU General Public License as published by

     the Free Software Foundation; either version 2 of the License, or

     (at your option) any later version.

     This program is distributed in the hope that it will be useful,

     but WITHOUT ANY WARRANTY; without even the implied warranty of

     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

     GNU General Public License for more details.

     You should have received a copy of the GNU General Public License

     along with this program; if not, write to the Free Software

     Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA  02111-1307, USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this

when it starts in an interactive mode:

     Gnomovision version 69, Copyright (C) 19YY NAME OF AUTHOR

     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

     This is free software, and you are welcome to redistribute it

     under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the

appropriate parts of the General Public License.  Of course, the

commands you use may be called something other than `show w' and `show

c'; they could even be mouse-clicks or menu items--whatever suits your

program.

You should also get your employer (if you work as a programmer) or your

school, if any, to sign a "copyright disclaimer" for the program, if

necessary.  Here is a sample; alter the names:

     Yoyodyne, Inc., hereby disclaims all copyright interest in the program

     `Gnomovision' (which makes passes at compilers) written by James Hacker.

     SIGNATURE OF TY COON, 1 April 1989

     Ty Coon, President of Vice

This General Public License does not permit incorporating your program

into proprietary programs.  If your program is a subroutine library,

you may consider it more useful to permit linking proprietary

applications with the library.  If this is what you want to do, use the

GNU Library General Public License instead of this License.
