ZPD Decision Module LUT and Cut Configuration

Decision Module Cuts

• Create a text file with the cuts you want to use. The format is:

  # Decision Module Cuts
  # pT in GeV, z0 in cm
  
  # Cuts for each decision bit and seedtype (0=A10, 1=A7)
  #  bit seed minPt  minDip maxDip minZ0 maxZ0 maxZ0err maxMiss
  cut  0  0   0.800  -4.0   4.0    -128  127    15       1
  cut  0  1   0.800  -4.0   4.0    -128  127    15       1
  cut  1  0   0.200  -2.0   3.0     -15   15    15       1
  cut  1  1   0.200  -2.0   3.0     -15   15    15       1
  cut  2  0   0.200  -2.0   3.0     -10   10    15       1
  cut  2  1   0.200  -2.0   3.0     -10   10    15       1
  cut  3  0   0.300  -2.0   3.0      -6    6    15       1
  cut  3  1   0.300  -2.0   3.0      -6    6    15       1
  cut  4  0   0.250  -3.0   3.0     -10   10    15       1
  cut  4  1   0.250  -3.0   3.0     -10   10    15       1
  cut  5  0   0.250  -3.0   3.0     -10   10    15       1
  cut  5  1   0.250  -3.0   3.0     -10   10    15       1
  cut  6  0   0.250  -3.0   3.0     -10   10    15       1
  cut  6  1   0.250  -3.0   3.0     -10   10    15       1
  cut  7  0   0.250  -3.0   3.0     -10   10    15       1
  cut  7  1   0.250  -3.0   3.0     -10   10    15       1
  
  # Mask bits: should cut include A10/A7 and/or sec0/sec1 ?
  #    bit A10  A7 sec0 sec1
  mask  0   1   1   1   1
  mask  1   1   1   1   1
  mask  2   1   1   1   1
  mask  3   1   1   1   1
  mask  4   1   0   1   1
  mask  5   0   1   1   1
  mask  6   1   1   1   0
  mask  7   1   1   0   1
  

  The cuts and masks can be in any order. If any cut or mask is missing, that cut will not be used.
  
  
• Run L1DctConfig/dumpZpdCuts <inFile> <outFile>
  e.g.
  • cd ~bailey/dev/teststand
  • srtpath
  • dumpZpdCuts cuts.txt zpdCuts.xtc
  Use an outFile extention of .lut to create a text format file instead of the binary XTC file.
  
  
• Copy the XTC file to /nfs/bbr-srv02/dataflow/7F/06/app/DczConfig/zpd
  (Eventually this will go in a database instead)
  
  
• Edit /nfs/bbr-srv02/dataflow/7F/06/app/DczConfig/zpdLutList.txt to include the cuts file you want to load.
