Using Simulation Data
=====================

Versions
--------
The current available CSST simulation data products are not versioned.
Therefore, in pipeline system, we use ``ver_sim`` keyword in code (e.g., ``CsstMsDataManager``).
The ``ver_sim`` uses a ``C{X}.{Y}`` format string, where
``X`` denotes the Cycle during which the simulation is released,
and ``Y`` denotes the serial number.
For example, ``C5.2`` represents for the second released version of simulation in Cycle 5.


Server details
--------------

Server
   ``dandelion``.
   The ``IP``, ``Username`` and ``Password`` are available via request to ``csst_das@nao.cas.cn``.
Simulation data path
   - ``C5.2``: ``/nfsdata/share/csst_simulation_data/Cycle-5-SimuData``
   - ``C3``: ``/nfsdata/share/csst_simulation_data/Cycle-3-SimuData``

.. note::
    Presently, the ``CsstMsDataManager`` only supports ``C5.2`` simulation.
