We updated our automated processing scripts in early November, and unfortunately, the scripts did not create master flat-fields properly.  We have reprocessed the images over the past few days; everything is now corrected.  The error may cause a small shift in your photometry, so we suggest that you look at a couple of nights and ensure your previous results compare ok with the new results; if not, replace your estimates in the AID.  The nights in question:

BSM: 101113-101119

W28: 101029-101119

W30: 101029-101119

We apologize for any inconvenience that this has caused.
