    List of problems for CRATE 3

  • ch 75 = 5TC08 NOT on the bodyCout-list

    List of problems for CRATE 4

  • did not triggered

    List of problems for CRATE 5

  • ch 88-95 , looks like lost patch JP4, Brd4, Cr 5, was present the day before
  • ch44=8TD09 IS masked out, see the spectra at the end , so it is NOT hot for the trigger
  • ch 97-103 shift in the threshold for JP1 brd4, cr 5 ???
  • ch 55 = 8TE12, ch 49=8TE02, ch43=8TD08, ch 96 = 8TD04, OK all on the bodyCout-list

    Bonus

  • since spectra from all other towers looks similar (for a regular run), we need to set our thresholds higher in order to avoid prescaling. From the pi0 analysis for different triggers it looks like the HT1 and HT2 correspond rather to the transverse energy of 1 and 2 GeV, respectively.
  • To answer if a new tower is hot it is very desired to have fast access to the rates from all jumpers based on the STAR DAQ files. Can anyone prepare a how to? The method I'm using (looking on the ADC spectra) is not reliable - I lost a good day for the 8TD09 thinking the mask is not working. Probably it worked all the times.
