SLS pipeline ============ Instrument correction --------------------- 概述 `````````````````` `csst_ms_sls_instrument` 程序包是应用于CSST无缝光谱模块的仪器效应改正程序,无缝光谱模块包含12个9k×9k探测器,每4块探测器对应1个波段,每个波段的部分仪器参数如下: - GU: 660×660″ field of view from 255-400nm with a plate scale of 0.074″/pixel - GV: 660×660″ field of view from 400-620nm with a plate scale of 0.074″/pixel - GI: 660×660″ field of view from 620-1000nm with a plate scale of 0.074″/pixel `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 数据产品 `````````````````` `csst_ms_sls_instrument` 将从`csst_common.CsstMsDataManager` 获取0级数据和参考文件。0级数据是有一个扩展的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。 .. _DataModel: https://csst-tb.bao.ac.cn/code/csst-l1/csst-l1doc/-/blob/main/docs/source/sls/data_model.md CSST无缝光谱的1级数据产品是三个扩展的fits文件,扩展内容如下表所示: +-----------------+---------+-------------------+ | Extension Name | bunit | comment | +=================+=========+===================+ | SCI | e-/s | science image | +-----------------+---------+-------------------+ | ERR | e-/s | error array | +-----------------+---------+-------------------+ | DQ | unitless| data quality array| +-----------------+---------+-------------------+ Position calibration --------------------- `csst_ms_sls_position` package.
