On August 8, BSMD peds in the offline DB where corrected for day 47.

Runs minb 34 & 74 were used to determine and upload DB peds.

 Goal: reco isolated gammas from bht0,1,2 -triggered events 

Method: identify isolated EM shower and match BSMD cluster energy to tower energy, as exercised earlier on [node:1176

 Peds from run minB 17 were used as reference

Note the different time scales on the Y axis. 

here are some presentations from the run 8 trigger planning.

Method:

 from _private_ production w/o zero BSMD suppression we look at pedestal residua for raw spectra for minb events.

 Goal: determine absolute calibration of BSMDE,P planes

Method: identify isolated EM shower and match BSMD cluster energy to tower energy

Smd cluster finder with sliding window of 3 strips + one strip on each end (total 5 strips) applied to all 9000 BSMDE,P strips, one gamma per event

 One dimensional  BSMD cluster finder is insensitive to single dead strips and module boundaries for the phi strip.

 Goal: test SMDE cluster finde

For every strip we find the closest tower and determine the distance between tower center and strip center.

 Goal: study SMDE energy resolution and cluster shape for single particles M-C

Input: single particle per event, fixed ET=6 GeV, flat eta [-0.1,1.1], flat  |phi| <5 deg, 500 e

 Below are studies of BSMD response and calibration algo based on BMSD response to single particle M-C
