`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:
+-----------------+----------------------------+-----------------+
| Reference file | Description | Keyword |
+=================+============================+=================+
| Gain map | gain array(9k×9k) | R_GAIN |
+-----------------+----------------------------+-----------------+
| Superbias | superbias file(9k×9k) | R_BIAS |
+-----------------+----------------------------+-----------------+
| Superdark | superdark file(9k×9k) | R_DARK |
