US Optical Installation Summary
Maintained by: RJM
Last Update: Feb. 12, 2002
A summary of the scan results for all of the US EB modules can be seen in the Postscript files listed below:Average response vs. Module using Larry Nodulman's peak analysis for Cs Scans
Average response vs. Module using CERN's (Bob Stanek) peak analysis for Cs Scans
These plots have been generated from a summary ntuple (modules.ntp, bsmodules.ntp) that contains one row for each layer for each PMT for each module. The ntuple contains the following 14 columns:
MODL SCAN LAYR CELL PMT SIDE NTILE SIGMA SO-E S0+E NBAD STILE SGEOM ADCAVG, where
- MODL is the module number;
- SCAN = 1 (2 ) for LED (Cs);
- LAYR = 0 (1:11) for samples normalized to 100 over all tiles on this PMT (within a tile layer);
- CELL = nxx with n = 0:3 for readout depths A:D, and xx = the eta index of the cell;
- PMT = the PMT number;
- SIDE = 1 (2) for Odd (Even) PMT;
- NTILE is the number of tiles in the sample;
- SIGMA = the rms variation of the sample;
- SO-E (SO+E) = the rms variation of the Odd - (+) Even sides of the tiles divided by sqrt(2);
- NBAD = the number of tiles in the sample that are less than 70% of the average;
- STILE = the rms variation in this sample due to tiles: Sqrt{<[Odd PMT - <Odd PMT>]*[Even PMT - <Even PMT>]>};
- SGEOM = the rms variation between layers in the sample :Sqrt{<(layer normalized - cell normalized)^2>};
- ADCAVG = the average ADC peak for this sample.
