Online DQM

Description

The current line is to monitor online as much as possible. The histograms are organised in what is called DQRegions. The two main branches are "L2" and "EF" groups, then there are FEX and Hypo groups. The overall organisation is presented on the plot below:




Where it was possible checks not requiring reference histogrm were used. For all other cases a Kolmogorov test agains a reference hisgorams was used.
The refenrece histograms were obtained with Monte Carlo QCD dijets event samples.
