Hi, I have several questions/problems that I need more information on to make sure that the readout software is working. In taking our slic output monte carlo files for 1.92 GeV running (beam background and tridents), we have a steering file that can produce output files for different types of triggers (singles0, singles1, pairs0, pairs1) that have the same settings that were used for events in December: org.hps.steering.readout.EngineeringRun2014PrescaledTriggers.lcsim The input file I use is at /work/hallb/hps/holly/debug/egsv3-triv2-g4v1_s2d6_1.slcio If I run the steering, I observe several things: 1. The number of pairs being looked at is significantly small (on the order of 2/100k events). Does this make sense? The number of singles being considered was around 7k. So is everything else just background? 2. In the terminal screen shot below, I commented out the other FADC trigger drivers and only ran singles0. The output file is at : /work/hallb/hps/holly/debug/out.singles0.slcio The corresponding log file is out.triggers.singles0 It only outputs two events that have passed trigger cuts despite my specifying a singles only cut. I am not sure why only 2 events were passed to the pairs trigger cut. I would think there should be more pairs considered. Is there a bug in the FADCPrimaryTriggerDriver? The defaults for pairs looks wide enough for singles, but it somehow only sees a few for consideration. Somehow, specifying a singles cut is still losing out when it is considered for pairs. 3. For events that don't pass cuts, empty slcio files are produced. Basically if I run the steering over the input file as it is, I get one good output file that is from pairs0. I guess I would like some input from those who produce the monte carlo that this makes sense as well as those who wrote the trigger drivers. I don't understand these results.
