production of binary events for L2 algos

 Here is prescription how to convert any muDst to the binary event format, needed to run L2-algos stand alone (by multiTest.C)

Let me start with a warning - this procedure requires execution of some additional code not relevant for this task ( being production of binary event files), but I wanted to reuse existing offline trigger simu code and there was no consensus how to rearrange it.

The goal is to produce events consisting of 2 data blocks : BTOW & ETOW - equivalent to raw data saved in the daq file.

  1. Prescription to produce R9067013.eve.bin from muDst from  run9067013 : 
    mkdir aaa
cd aaa
mkdir out2
stardev
cp $STAR/StRoot/StTriggerUtilities/macros/rdMu2binL2eve.C .
cp /star/institutions/mit/balewski/2008-L2events/R9067013.lis .
root4star -b -q rdMu2binL2eve.C >& L1 &
    You need no private code, just the .C macro, setup to read the run-list, muDst must still exist on the disk (fix it if needed).
  2. Inspect the .C macro to find out how to change # of processed events, # muDst to read in. If you use muDst from M-C you need to activate useMC-switch in the macro and decide on the time stamp - this is on of this irrelevant things I have warned you. Current default is reasonable. 
  3. Output: the binary event file (R9067013.eve.bin) will show up in the 'aaa/' directory. The content of binary events is different for real data vs. M-C. This can be fixed later (by Ross?), but for now you must take it in to account while reading such events by multiTest.C
    • binary events for real data contain raw BTOW & ETOW data blocks. This is certainly true for the Endcap, I'm less sure for the barrel, since I'm forced to use  StEmcADCtoEMaker and I do not if it removes ADC for masked towers. You need to figure it out. The main point is for real data you will see 4800+720 non-zero ADCs before pedestal subtraction. This is exactly what L2-algo receive on-line.
      Note, your L2-algo will receive data after ped subtraction.
    • binary events for M-C contain only fired towers, peds are not added, nor smeared. Therefore, you must use different L2-pedestal files while reading such events, with ped set to 0 - otherwise the common L2-calib algo will subtract peds anyhow.

      This could be changed if one activates properly slow simu for BTOW & ETOW - talk to Ross. The advantage would be identical L2-peds & status tables could be used for M-C events and for real data. The disadvantage of using slow simu is now you must set DB time stamp during production of binary events  and have L2-peds for exactly the same time stamp - or you will end up residual energies seen by L2-algos.

       

  4.  QA output: look at the file: aaa/out2/run9067013.l2ped.out it will show pedestal residua using online L2 peds as R9067013. This is one of those confusing steps. While producing binary events  the rdMu2binL2eve.C runs also L2-ped algo (I can't turn it off due to code dependencies), but L2-ped does NOT affect content of the output binary event file. But you can use L2-ped output to monitor if reasonable ADC have been found in muDst.
    This is an ASCII file, on the top there are 720 Endcap pedestals residua:

    The above files are for real data, when peds seen by L2-ped algo match the real pedestals.

    If you display the same file for M-C events, you will see just high-energy ends of ADC spectra, because at this moment binary events for M-C do not include pedestals.
