Regrading C M1591: due to Noise |

While recent calibration done by Maren with a few new modules suggest that this conversion is 43.7electrons per 1 VCal (the number from Danek).
I re-run MoreWeb analysis with 44e/Vcal for modules that are graded C for high noise (>300e).
1) Change 50-->44 in
(1) Analyse/AbstractClasses/TestResultEnvironment.py: 'StandardVcal2ElectronConversionFactor':50,
(2) Analyse/Configuration/GradingParameters.cfg:StandardVcal2ElectronConversionFactor = 50
(3) Analyse/Configuration/GradingParameters.cfg.default:StandardVcal2ElectronConversionFactor = 50
2) remove all SCurve_C*.dat files (otherwise new fit results are not written in these files)
3) run python Controller.py -r -m M1591
M1591:
- all three T grade C due to Mean Noise > 300 for ROC0 and/or both ROC0 and ROC1
- after rerun MoreWeb all but one grades are B on individual FT page but in Summary pages grades still C???
- second time at -20C: grade C is due to trimming fails in ROC0: 211 pixels have too large threshold after trimming
Trimming to be checked!!! |
To correct the Summary page one needs to remove rows from DB with C grade from previous data analysis (that for some reason stayed in DB)
using python Controller -d and then run python Controller -m MXXXX
To the directory :~/L1_DATA/WebOutput/MoReWeb/FinalResults/REV001/R001/M1591_FullQualification_2020-02-28_08h03m_1582873436/QualificationGroup/ModuleFulltest_m20_2
file grade.txt with a content "2" (corresponds to grade B) has been added. Hence this test grade has been changed from C to B.The reason is that 211 pixels fail trimming (threshold is outside boundary) is a too low trim threshold: VCal=40. From now on 50 will be used. |
