With DAQ1000, the RTS libraries are now in $STAR/StRoot/RTS. This enables the FTPC noise finder programs, GetGain and FindNoise, to run on the rcas machines as well as on virgo-run09. If you login as ftpccrew on virgo-run09, the library environment will be set up automatically for you. $PATH will contain the SL09b version of the FTPC online library so you can execute GetGain and FindNoise. CURRENTLY DOESN'T WORK ON rcas ===================================================================== The advantage of running on an rcas machine, is that you do NOT have to copy the daq files to the virgo-run09 data disk, you can get a daq file from HPSS and use it directly from /star/data03/daq/.... The disadvantage is that you have to create the GetGain and FindNoise binaries in your working directory: starver SL09b this is the STAR library version the FTPC online library currently uses (2009-07-17) cvs co online/ftpc/NoiseFinder cd online/ftpc/NoiseFinder mkdir bin cvs checkout prunes empty directories make all cd ../../.. ln -s online/ftpc/NoiseFinder/bin/GetGain GetGain ln -s online/ftpc/NoiseFinder/bin/FindNoise FindNoise ===================================================================== In 2010, the pulser signal moved. Before you make a gain table, determine at which timebin the pulser signal is located by looking at a pulser run with the pad monitor. Determine a lower and an upper timebin search limit - they should be 50 counts apart. minTime maxTime <2010 50 100 2010 20 70 2011 50 100 Then to run in your working directory: mkdir gain_table This will be the directory in which the gain table (GainTable.dat) from a pulser run is stored. GetGain -M minTimebin -X maxTimebin <pulserfile> >& GetGain.log& minTimebin is the lower limit on the pulser timebin search area maxTimebin is the upper limit on the pulser timebin search area pulserfile can be either from the event pool (in this case you must run on virgo-run09) or a daq file you have downloaded from HPSS Output files: GetGain.log Gain.ps Gain.root gain_table/GainTable.dat The Gain.ps file contains 28 pages of histograms: page 1->20 average charge/pad one histogram/sector => one page/padrow page 21 empty page 22 mean sector charge, sec vs. row *page 23 mean pad charge, pad vs. row dead pads = white noisy pads = red *page 24 gain_table/GainTable.dat corrected pad charge, pad vs. row page 25-27 empty page 28 average timebin value for FTPC West and East The second step is to run FindNoise FILE, this time FILE is a data run. FindNoise uses the gain table in gain_table/GainTable.dat, and produces a new gain table file: gain_table/NoiseCorrected_GainTable.dat FindNoise <filename> >& FindNoise.log1& filename can be either from the event pool or a daq file default noisecut = noisecutWest = noisecutEast = 1000 Output files: FindNoise.log1 NoiseFinder.ps gain_table/NoiseCorrected_GainTable.dat Use the NoiseFinder.ps file to determine noisecutWest and noisecutEast then rerun FindNoise FindNoise -W [noisecutWest] -E [noisecutEast] <filename> >& FindNoise.log2& Output files: FindNoise.log2 NoiseFinder.ps gain_table/NoiseCorrected_GainTable.dat Use this file to create the offline database Calibrations_ftpc/ftpcAmpSlope table The NoiseFinder.ps file contains 25 pages of histograms: page 1->20 average charge/pad one histogram/sector => one page/padrow page 21 empty page 22 mean sector charge, sec vs. row *page 23 mean pad charge, pad vs. row dead pads = white noisy pads = red *page 24 gain_table/GainTable.dat corrected pad charge, pad vs. row *page 25 gain_table/NoiseCorrected_GainTable.dat corrected pad charge, pad vs. row Then use the NoiseFinder utility, WriteAmpSlope_cc.so in $FTPC/lib, to create a gain table file, ftpcAmpSlope.C, for the Calibrations_ftpc/ftpcAmpSlope in the offline database. Or use the NoiseFinder utility, WriteDaqFlagg_cc.so in $FTPC/lib, to create a bad pad file, ftpcDaqFlagg.dat, for DAQ. The FTPC NoiseFinder utilities WriteDaqFlagg and WriteAmpSlope are run in root4star using shared libraries in $FTPC/lib. These shared libraries are created as follows: root4star root4star [0] .L WriteDaqFlagg.cc+ Info in <TUnixSystem::ACLiC>: creating shared library /mnt/data2/pclusa8 /FtpcOnlineLibrary/online/ftpc/NoiseFinder/utils/./WriteDaqFlagg_cc.so root4star [1] .mv WriteDaqFlagg_cc.so $FTPC/lib root4star [2] .L WriteAmpSlope.cc+ Info in <TUnixSystem::ACLiC>: creating shared library /mnt/data2/pclusa8 /FtpcOnlineLibrary/online/ftpc/NoiseFinder/utils/./WriteAmpSlope_cc.so root4star [3] .mv WriteAmpSlope_cc.so $FTPC/lib root4star [4].q WriteDaqFlagg.cc ================ WriteDaqFlagg.cc reads in the FTPC NoiseFinder output file (GainTable.dat) and writes out a file (ftpcDaqFlagg.dat) with which noisy FTPC pads can be masked out in DAQ once Tonko receives a copy. To run in the FtpcOnlineLibrary environment: root4star root4star [0]gSystem->Load("WriteDaqFlagg_cc") root4star [1]WriteDaqFlagg() If you use WriteDaqFlagg(), the gain_table/GainTable.dat file will be read in. You can specify the input file by replacing inputFile with the correct filename in the root4star command WriteDaqFlagg("inputFile") Outputfile: ftpcDaqFlag.dat To maintain a record of which pads are masked out it is ESSENTIAL to archive the ftpcDaqFlagg.dat files which are sent to Tonko. The files are archive on virgo-run09 in /data/FlaggedDaqPads/YYYY YYYY is a sub-directory with YYYY = year cp ftpcDaqFlagg.dat /data/FlaggedDaqPads/YYYY/RUNNUMBER_ftpcDaqFlagg.dat RUNNUMBER is the run number of the file used to produce the GainTable.dat file WriteAmpSlope.cc ================ WriteAmpSlope.cc reads in the FTPC NoiseFinder output file from ./gain_table/NoiseCorrected_GainTable.dat) and writes out an ftpcAmpSlope.C file which can be added to the offline database in Calibrations_ftpc/ftpcAmpSlope. To run in the FtpcOnlineLibrary environment: root4star root4star [0]gSystem->Load("WriteAmpSlope_cc") root4star [1]WriteAmpSlope() If you use WriteAmpSlope(), the gain_table/NoiseCorrected_GainTable.dat file will be read in. You can specify the input file by replacing inputFile with the correct filename in the root4star command WriteDaqFlagg("inputFile") Output file: ftpcAmpSlope.C This file should be added to the STAR data base using the DataBaseInstructions described in /afs/rhic.bnl.gov/star/users/jcs/public/DataBaseInstructions
