Ped deviation monitoring (10/03/2008)

The following plots show the evolution with time of the pedestal deviation for LEX1,HEX1,LEX8 and HEX8 .I retrieve use the mean and the rms of the distribution of CALPEDSANALYZER : root file CALPEDSANALYZER and canvas CalXAdcPedPedMeanDeviation_LEX1_TH1 ( LEX1,HEX1,LEX8 and HEX8).
I put the data into a histogram and fit with a Gaussian (see plot). The reported value is the mean of the gaussian (with 3 parameters, N ,mu, sigma) ( which give the peak of the distribution) and the error bar is the width of the Gaussian sigma
Image Added

the time range is more or less 30 days


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

Wiki MarkupThe following plots show the evolution of the fitted parameter *\[0\]* as a function of time for both FLE and FHE. This parameter is likely to described the mean FLE (FHE) threshold.

• The red cross are the obtained values and the error bars are the errors given by MINUIT
• First plot is the fitted FLE threshold as a function of time and the second plot is the same but for FHE threshold
