DECam Calibration Files

Current calibration files used by the community pipeline can be found here:
ftp://ftp.noao.edu/pub/valdes/DECamCPCalFiles150123/

The name of the files available in that directory mean:

  • bpm - bad pixel masks
     
  • fringecor - fringe templates
     
  • hfix - header fixing values
     
  • linearity - linearity coefficients
     
  • starflat - star flat derived illumination flat
     
  • wcs - WCS distortion coefficients
     
  • xtalk - crosstalk coefficients
     
The timestamps like 56475 and 56534 are the MJD of when they become applicable.  Currently the only changed calibration is starflat.
