# L1-MBI Data model
- 每一个模块的结果单独开一个section，以COMMENT分隔（参考0级数据）
- 精简、丰富、修改每个关键字定义的comment
- `---`表示在模块算法失败的情况下按照实际情况填写，比如无论模块是否成功，时间戳都应该填写实际值
- keyword开头是“-”号的，根据理解和最终的产品无关，建议去掉
- keyword开头是“*”号的，表示有所修改，请检查是否需要，完善注释，并检查对fill value的设置是否合理
- flux模块中的天光背景测量已经移动到instrumens，请把该数值利用zp转换为SKY_MAG（单位mag/arcsed^2）
- 版本，完成时间，状态三个参数的name进行了统一，分别以VER_，STM_，STA_开头
