Summary of MOPS_depthloss_test130715

MOPS has noted often in the past of signal-to-noise issues (primarily not reaching the detection depths expecting and varying signal-to-noise measures). This has been traced back to an incorrect propagation of the covariance in the difference images.

Alan suggested a couple of chunks for comparison testing with a more appropriate covariance propagation (at least for all but the brightest sources)

• TJD 56065, chunk 152.OSS.D.Q.w as a night where can compare with both the original diffim photometry and also the chip-level photometry (20120518)
• TJD 56477, chunk 166.OSS.J.Q.w for a very recently observed set (20130704)

Reprocessing details -- started on 20130715

• gpc1db warp label, data_group -- meh_mopstestoss130715_nodualwav, OSS.20120518 and OSS.20120704 (unchanged)
• gpc1db diff label, data_group -- meh_mopstestoss130715_nodualwav, OSS.20120518 and OSS.20120704 (unchanged)
• gpc1db publishing label -- meh_mopstestoss130715_nodualwav
• gpc1db publish_id range: 833334--833411 (all inclusive)
• datastore time registered starting 2013-07-17T00:45:16Z

It is important to note that these reprocessed diffims also included the dual convolution option also turned off (though only a small % wanted dual as seen from the original processing)

More will be added to this page as time allows.
