I use two datasets to QA BSMD channels: zero-suppressed data from L2W events (fills 10383-10507) and non-zero-suppressed data from online monitoring (fills 10436-10507) (note that at the moment I am not examining the time dependence of BSMD status).  NZS data is used to QA the pedestal peak of a channel, while high-energy ZS data is used to QA the tail.

Next, the ZS data are compared to the ZS data from the previous channel to check for copycat channels.  Then three quantities are calculated: the ratios of the integrals from 300-500, 500-800, and 800-the end of the spectrum to the total integral of the channel.  Each of these quantities must then fall within the following cuts: .0001-.02, .00004-.02, and .00005-.02 respectively.  Here is a sample distribution:

Also, the spectra for the strips in module 3, with status, are attached.  I have not had a chance to look closely at any other modules yet.
