FPS test details

1. Run Type
   Information on the run type is obtained from the run header RHDR bank. The settings of all the run type mask bits are written to the FPS text file. The required mask for Salt Neutrino runs is:
   
   Neutrino
   D2O
   Salt
   Comp Coils
   
   Runs with the UC bit set, pass the criterion for UC Salt Neutrino runs. If any other bits are set in this mask the test fails.

2. Trigger Mask
   Information on the trigger mask for a run is obtained from the TRIG bank. For Salt Neutrino runs all the following triggers must be active:
   
   NHIT100Med
   NHIT100High
   NHIT20
   ESUMHi
   OWLN
   OWLEHi
   PulseGT
   Prescale
   
   The trigger check also tests the threshold of the Nhit 100NMed trigger. The test will fail if it exceeds the value defined in the TFPS titles bank.
3. DQXX tests
   FPS tests the number of crates and PMTs online. Thresholds are set in TFPS for the minimum number of crates, PMTs, OWLS and BUTTS, and Necks online, and the test will fail if these criteria are not met. For a crate to be online, the global trigger must be enabled, and the high voltage must be on. For a PMT to be online, the sequencer, PMTIC, and RELAY must all be on.
4. Run Time Tests
   To evaluate the run time, FPS loops through all events, and takes the time difference between the first and last, as measured by both the 10MHz and 50MHz clocks. The code accounts for rollovers in the 50MHz clock and allows for the fact that the events may be out of order. Thresholds for the minimum run time for Neutrino and Neutrino UC bit runs are set in the TFPS bank. The test will fail if the 10MHz run time is shorter than the relevant threshold. There is also a maximum run time threshold. The amount of time cut out by the BURST cut, or RETRIGGER cut, taken from the /raa_com_subp_runlog_analysis/ common block, is also reported in the FPS text file. The Run Time Test will fail if more than a given fraction of the run, specified in TFPS, is cut by these cuts.
