[![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/)

## 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.

## `data manager` for MS MBI
