# PDR3 D/UD reprocessing

Due to processing failures, a small number of good exposures were not included in the coadds, resulted in shallower depths in several tracts in the D/UD layer.  The affected tracts are:

 filter tract g-band 8766, 9463 i-band 8524, 9463 y-band 8523, 8765

We have reprocessed these tracts and they are now as deep as they should be.  The reprocessed D/UD data can be found under pdr3_dud_rev on the database.  It includes not just the reprocessed tracts, but the entire D/UD data.  You can just change your SQL script to use pdr3_dud_rev (e.g., FROM pdr3_dud.forced -> FROM pdr3_dud_rev.forced).  The reprocessed fits files can also be found in this directory tree.  Updated QA plots can be found below.

Note that, due to the way the pipeline works, all the filters in these tracts have been updated (i.e., not just the filters listed above).  When you revise your analysis with the new data, be sure to update all filters in these tracts.
