01 DB peds R9069005, 9067013

 Pedestal residua for 434 zero-bias events from run 9069005.

The same pedestal for all caps was used - as implemented in the offline DB.

Fig 2.  Run 9067013, excluded caps >120.  All 4800 tiles, pedestal residua from 100 st_zeroBias events. Y-axis [-50,+150].

Fig 3.  Run 9067013, excluded caps >120. Pedestal corrected spectra for all 4800 tiles, 10K  st_physics events. Y-axis [-50,+150].

Dead MAPMT results with 4 patches 4 towers wide.

Run 9067013, input =100 events, accept if capID=124 , raw spectra.

There are 4 BPRS  crates, so 1200 channels/crate.  In terms of softIds it's

PSD1W:  1-300 + 1501-2400
PSD19W: 301-1500
PSD1E:  2401-2900 + 4101-4800
PSD20E: 2901-4100

Why only 2 channels fired in crate PSD20E ?
