Introduction:
-------------
These are files that were processed with the DES Y3 data management
pipeline. They use updated image-level calibrations for flat fielding
etc. However, the processing pipeline has never been tested in the
extremely dense fields near the Galactic plane, so the output
(especially the PSFEx estimates and resulting SExtractor catalogs)
could be complete junk.

Within each tarball, the files are organized by CCD. Filenames can
usually be decoded as:
 D{expnum}_{band}_{ccdnum}_{version}_{filetype}.fits

A more detailed file description is provided below.

File Description:
-----------------
*_immask.fits.fz - DES reduced image for each CCD in the exposure
*_fullcat.fits - SExtractor catalog for each CCD image
*_sextractorPSFEX.pdf - PSF estimate from PSFEx for each CCD image
Merg_allZP_* - Merged list of zeropoints for all CCDs (this may be complete junk)
