-Reference stack using data from 2010+2011, a balance of N input warps versus best seeing, excluding exposures with large background, low zeropoints, and large elongation. 
+Exposure reprocessing was done for only a limited number (~150) of the best images from 2010+2011 to provide a balance of N input warps versus best seeing, excluding exposures with large background, low zeropoints and large elongation. Processing chip-warp and the refstack itself has the same label, data_group
  * label: MD10.refstack.20120705
  * data_group: MD10.refstack.20120705
 
+Replacement refstack made using the 20120705 reprocessed exposures
  * label: MD10.refstack.20120804
  * data_group: MD10.refstack.20120804
