Compare to thoughts I added to https://confluence.slac.stanford.edu/display/DC2/Monitoring
on 5 Oct 2006.
Note: I did a lot of rearranging of this section on 13 Mar, but I've added only a few items, mostly in last two sections before the email.
Daily standard plots
This includes a lot more than just CAL info, but there are so many parallel features among the instruments that we might as well list them all.

Strip chart of sigma of overall CAL LEX8 and HEX8 pedestal width distributions calculated in Item 1 of 24 Jan 2007 email message below. Measures average noise and its variation through the day, through time.
Note: see comment on time binning below.
Strip chart of mean and rms of the 3 ratio centroids (P/M, P/p, M/m) for CAL calculated in Item 2 of 24 Jan 2007 email message below. Measures global PDA bond stability through time.
Note: see comment on time binning below.
Strip chart of median raw CAL energy sum for events with non-zero CAL energy sum.

List of GCFEs that gave no HEX1 data in that day (or orbit, depending on duration of summary report). This flags failed channels for small PIN diodes.
Added 6 Apr 07 Occupancy ratio summary. The intent is to find specific GCFEs for which the current occupancy has changed from their typical occupancy. See occupancy ratio summary discussion@Occupancy Ratio Summary below for further details.
Added 6 Apr 07 Pedestal noise ratio summary. The intent is to find specific GCFEs for which the pedestal width has changed from its typical value. See noise ratio summary discussion@Noise Ratio Summary below for further details.

This gives an overall measure of whether there were diode bond failures. It won't tell us which CDE is bad, and there are some
systematic problems with certain channels on each AFEE board (remember David figured that out while he was at SLAC?). Note added 12 Mar 07: perhaps we should exclude those known systematic issues from board layout in these histograms.
It won't add much run time to the digi reporting to calculate 16,000 gaussian fits, will it?
