HLT E/Gamma slice data quality plots documentation (DQMD)

This is the documentation for the E/Gamma data quality plots shown in the data quality monitoring display (DQMD) for the HLT at point 1. The following contains a table with a list of histogram names/tab names, a description of what they represent, a reference histogram and a trouble shooting guide for when the histogram is flagged red. The high level trigger is split into a second level (L2) and event filter (EF) part, in which the references are divided in an electron part (TRELE) and a photon part (TRGAM). The reference plots have been taken from collision run 153565. The plots contain either feature extraction (FEX) or hypothesis histograms.
General trouble shooting: If a histogram doesn't look like its reference this can have several causes. If it is a histogram in the event filter (EF) try to determine how the same histogram looks for the second level trigger (L2) if possible. This might indicate there is a problem in the trigger itself. If the L2 histogram is also not like the reference, you might want to inquire with the specific subdetector. Mostly this will be the liquid argon calorimeter, but when there is track matching involved, the pixel, sct and trt play an important role. The trt can only determine phi information in its barrel (abs(eta)<0.7), therefore, when the pixel and sct detectors are off the trackmatching in eta is worse.
