Calibrations

I have finished the reprocessing of the overall datasample in order to calibrate the BM on a run per run basis. The calibration files, that now are HUGE, cannot be stored under svn anymore. So I had to copy them under lustre and I am writing this email to document the actions that you have to take in order to USE the calibrations in your processing.

• the file where the calib files are defined is under config/file_stlist_FIRST.txt [l0reco project]

this file now points to the correct files:

• • spline_First_all_st0.root
  • spline_First_all_st2.root
  • spline_First_all_st4.root
  • spline_First_all_st6.root
  • spline_First_all_st1.root
  • spline_First_all_st3.root
  • spline_First_all_st5.root
  • spline_First_all_st7.root
  • spline_First_all_st8.root

Those spline files are kept under /lustre/bio/first/calib/

• so to use this new calibration in your processing you have to

-> COPY those files FROM /lustre/bio/first/calib/ to the config/ directory in your work area /first/rec/trunk/l0reco ) If you do not have the files in config/ but you'd like to keep them elsewhere, you just have to change the path in config/file_stlist_FIRST.txt) c) the calibrations are for ALL the production runs processed so far [the ones that you usually find UNDER production_root, reprocessed]. If you need a custom calibration for any other production run JUST ask me and I'll provide the necessary calibrations.

I am going to produce the v18 files with everything calibrated today. They will show up under /SAT/s/s371/PRODUCTION_root in the next hours and I'll take care of backup them under lustre.

Macro

Under macro/beam_monitor

• T0dch_new.C : is used to produce a list of T0s to be used in the electronics offset removal. To run it use:

root -b  -q T0dch_new.C\(\"intput.root\"\)

• STRelations_First.C :

config

T0s are kept in config/beammonitor_t0s.cfg and are in ns

Histo

• beammonitor/tdc_ : RAW time of TDC hits connected to a given channel [filled in TABMactDatRaw.cxx]
