CAL Trending
In this page a trending study of the LAT Calorimeter is presented.
- For the period between 09.01.2006 and 03.27.2008, a total of 362 LAT-22x runs were examined.
- Run 077012890 taken on 11.13.2006 was adopted as a reference run. This run was taken at room temerature.
Plots
Two sets of plots were generated:
- For each run, the distriution of Muon pedestals for that run were compared to those of the reference run. The resulting 361 historgams were drown as a time series in a 2D histogram. Plots with "Distribution of Pedestal Differnces: " show such plots.
- For each run, the distribution of Muon pedestal widths were plotted as a time series on a 2D histogram. Plots with "Distribution of Pedestal Widths:" show such plots.
These histograms were created for the four different energy ranges, LEX8,LEX1,HEX8, and HEX1. In all of the histograms, the value on th ex-axis represents the consequential number of the runs. The table attached shows these numbers as a function of the run number and the modified julian date the run was taken.
