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 use the 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
the time range is more or less 30 days
we see a clear trend that could explain the trend is FLE and FHE threshold.

The 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
