Detailed description of the data product

Also known as photflatcor image in DES terminology. This is an input calibration product to the DES pipeline.

The main elements inside this product are:

• ValidFromNight: Night from which the calibration product can be considered valid.

• Filter: The DECam filter name (DECAM_g, DECAM_r, DECAM_i, DECAM_z or DECAM_Y).

• CCDNumber: The DECam science CCD number (1 to 62).

• DataStorage: Element that links to a FITS file containing the CCD photflatcor calibration image.
