This directory and subdirectories contain sample calibration and configuration files used to process DECam images by the DESDM firstcut and finalcut pipelines into detrended images.
A fuller description of the processing steps is contained in Morganson et al. 2018.
Please note that the internal format of some of these files is not fully documented here, but mechanisms to read the contents of these files may be found embedded in the associated codes in the github repositories and elsewhere.
Please note that when a set of calibration file has separate entries by ccdnum and/or by filter, that only one ccdnum and/or filter sample element file is included here.
The set of sample cal/config of files included:
