LAC monitoring

• The following plots show the evolution, for POS (top) and NEG (bottom), of the LAC distribution mean value and RMS from the RECONHISTALARMDIST.Lac_Thresholds_FaceNeg_TH1_TowerCalLayerCalColumn_leftmost_edge_TH1 and RECONHISTALARMDIST.Lac_Thresholds_FacePos_TH1_TowerCalLayerCalColumn_leftmost_edge_TH1 plots with the moot key=2419 (most recent NomSciOps definition).

FLE and FHE monitoring

We used the reconhist file to monitor the FLE and FHE threshold.

Fitting procedure

For FLE, we fit the 'SuspCalLo_Highest0_EnergyDistribution_TH1' histogram with the following function :

...

f1 = ROOT.TF1("f1","([2]/pow(x,[3]))/(1+exp(([0]-x)/[4]))+[1]",300,2000)

Results

the following plot show the evolution of the fitted parameter 0 as a function of time. This parameter is likely to described the mean FLE (FHE) threshold.
