one cluster topology , definition of 'barrel cell'

Under:

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

2) BSMDE , 1+3+1 sliding cluster finder

Under:

 Goal: test SMDE cluster finde

Mapping, strip to tower distance

Under:

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

1) BSMD-E clusters, sliding max, fixed width

Under:

 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

1) M-C : response of BSMD , single particles (Jan)

Under:

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

10) SMD-P gain equalization , ver 1.1

Under:

Goal : predict BSMD-P relative gain corrections for every eta bin 

Method : find average slope per eta slice, fit gauss, determine average slope : avrSlope(iEta)

13) ver 1.2 : SMD-E, -P, status & relative gains, no Crate4

Under:

Automatic BSMD-E, -P   relative calibration and status tables. 

The second pass through both SMDE, SMDP was performed, learning from previous mistakes.
