How to make BGFilter tag bit plots

Begin:

1. Log in to one of the slac machine (yakut or noric)
2. In this example, release 22.1.1 is used
3. Some usual settings:

   > srtpath [enter][enter]
   > cond22boot
   

4. add package: RecoBGFilter HEAD, Elf, and workdir
5. Compile and Link:

   > gmake clean
   > gmake installdirs
   > gmake workdir.setup
   > gmake lib
   > gmake Elf.ElfUserXtcApp
   

6. Stage xtc file for the run you want: (ex: run 67676)

   > tcstage 0067676-001
   

   This file will be stage into: /nfs/babar/tcfiles
7. Make myelf.tcl in workdir:

   set ElfConfigPatchSet Run2
   set ElfHistoFileName myElf.root
   set ElfOutputCollection /work/users/[your user name]/elftest.xtc
   set ElfTuple root
   sourceFoundFile Elf/ElfProduction.tcl
   

8. If run more than once, don't forget to remove output. In my case they are in /nfs/sulky40/user02/work/users/hojeong/ dir.
9. Run:

   ElfUserXtcApp -n 10 -f /nfs/babar/tcfiles/babar-0067676-001.xtc myelf.tcl
   

   -n: number of events (-1 for all events)

Look at the result:

1. Look at the output root file: myElf.root
2. Histograms are in RecoBGFilterMon directiory
   • RecoBGFilter tagBits (inclusive plot: h1d2)
   • RecoBGFilter tagBitsExcl (exclusive plot: h1d3)
   • tagBitsRecoBGFilter (2-D inclusive plot: h2d1)
   • RecoBGFilter tagBitsCorrel (2-D correlation plot: h2d4)
   • RecoBGFilter tagBitsAntiCorrel (2-D anti-correlation plot: h2d5)
