Pedestal histograms for one complete run, for all four ranges of this CFE. Repeat this for a neighboring CFE.

GemConditionsWord==32 for r0264694008 and CalXtalID(14,4,0) using POS sides only

Mean/RMS for adcp0 is 582.102277 / 77.870177
Mean/RMS for adcp1 is 231.229641 / 59.862071
Mean/RMS for adcp2 is 512.500579 / 7.685434
Mean/RMS for adcp3 is 204.602856 / 0.998327

Gaussian fitting is difficult to make converge, hence the fit is constrained in the interval mean-2*rms,mean+2*rms

Mean/RMS for adcp0 is 582.102277 / 77.87017 Gaussian fit mean RMS 581.153117 5.609077

Mean/RMS for adcp1 is 231.229641 / 59.86207 Gaussian fit mean RMS 230.686616 0.829612

Mean/RMS for adcp2 is 512.500579 / 7.685434 Gaussian fit mean RMS 512.871404 3.383572

Mean/RMS for adcp3 is 204.602856 / 0.998327 Gaussian fit mean RMS 205.084367 0.602602

*adjacent channel

2D histogram (or scatterplot) of pedestal v. time since previous readout for all four ranges of this CFE for one complete run. Start with the x1 ranges. Stop if it's obviously uninteresting. Repeat this for a neighboring CFE.

All 4 ranges versus DeltaEventTime. There is a noticeable deltatime-dependent effect, with the pedestal becoming smaller when deltat increases.

*adjacent channel

Time series of pedestal for all four ranges of this CFE for one complete run. Start with the x1 ranges. Stop if it's obviously uninteresting.

All 4 ranges versus trigger time. No noticeable time-dependent effect.

Comparison of LEX1 in noisy and quiet run for LEX1


left: noisy, right: quiet

No noticeable differences in the pedestal fits. Note however that on the raw histograms:
noisy RMS is 34.672148
clean RMS is 2.030238

There are a few upper and lower outliers in the "noisy" run so when I cut lex1 to >100 and <1000 I get
noisy RMS is 2.137363
clean RMS is 2.030238
