`csst_ms_sls_instrument` 将顺序执行一系列的探测器效应改正，生成单次曝光图像预处理后的数据产品。该程序是用Python语言实现，代码地址：code_。



.. _code: https://csst-tb.bao.ac.cn/code/csst-l1/sls/csst_ms_sls_instrument

Input

``````````````````

`csst_ms_sls_instrument` 将从csst_common.CsstMsDataManager获取0级数据和参考文件。

0级数据是包含一个扩展的fits文件，头文件中存放着观测天区、曝光信息、探测器信息等，具体关键字说明参见 DataModel_，扩展的数据单元存放着原始观测图像。

参考文件列表如下,第一列是参考文件类型，第二列是文件说明，第三列是数据产品中记录文件名的关键字：
