The following plots show the evolution with time of the pedestal deviation for LEX1,HEX1,LEX8 and HEX8. I retrieve the mean and the rms of the distribution of CALPEDSANALYZER : CalXAdcPedPedMeanDeviation_LEX1_TH1 ( LEX1,HEX1,LEX8 and HEX8). the time range is more or less 30 days


we see a clear trend that could explain the trend is FLE and FHE threshold.
