## csst_proto 
[![Documentation Status](https://readthedocs.org/projects/csst-proto/badge/?version=latest)](https://csst-proto.readthedocs.io/en/latest/?badge=latest)
 
CSST L1 pipeline prototype.

## homepage

This code is available at *CSST GitLab*:
- [https://csst-tb.bao.ac.cn/code/csst-l1/csst_proto](https://csst-tb.bao.ac.cn/code/csst-l1/csst_proto).

## documentation

A sphinx-based documentation is available at
- [https://csst-proto.readthedocs.io/en/latest/](https://csst-proto.readthedocs.io/en/latest/)

## dependency

- numpy~=1.20.3
- joblib~=1.1.0
- astropy~=5.1

## installation

`csst_proto` can be installed with the following shell command

```bash
git clone https://csst-tb.bao.ac.cn/code/csst-l1/csst_proto.git
cd csst_proto
pip install -r requirements.txt
python setup.py install
```

or a single-line command

```bash
sh -c "$(curl -fsSL https://csst-tb.bao.ac.cn/code/csst-l1/csst_proto/-/raw/main/install.sh)"
```

## instruction

A simple example on how to use this package:

```python
from csst_proto.top_level_interface import flip_image
from astropy.io import fits

# read an L0 image
img = fits.getdata("CSST_MS_SCI_06_L0_img.fits")
# flip the image
img_flipped = flip_image(img=img)
```

## algorithm description

The `csst_proto` uses an awesome algorithm based on `numpy.ndarray` indices to flip images.

---

## `git`: connecting collaborators

A very brief example of using `git`:

```bash
# global setting for git (name and email address)
git config --global user.name "BO ZHANG"
git config --global user.email "bozhang@nao.cas.cn"

# initialize a repository with main branch
git init --initial-branch=main
# clone a remote repository
git clone https://csst-tb.bao.ac.cn/code/csst-l1/csst_proto.git
# add some_module.py to version control system
git add ./some_module.py       
# commit the changes  
git commit -m "added some_module" 
# add remote repository link
git remote add origin https://csst-tb.bao.ac.cn/code/csst-l1/csst_proto.git
# push changes to remote repository
git push origin main
# pull remote updates
git pull origin main
```

## `data manager` for MS MBI

```python
import os
from csst.ms.data_manager import CsstMscDataManager
from csst.ms.backbone import CCD_ID_LIST

# initialize data manager
dm = CsstMscDataManager(
    ver_sim="C5.1", dir_l0="/data/sim_data/MSC_0000100", dir_l1="/home/user/L1Pipeline/msc/work")

dm.set_ccd_ids(CCD_ID_LIST)

print("----- available ccd_ids -----")
print(dm.available_ccd_ids)
for ccd_id in dm.target_ccd_ids:
