How to change the calibration constants used by recon?

(by Dave Smith, for the CAL case. )  There are 5 types of CAL calib.xml files, called

  • asym   = light asymmnetry
  • ci_intnonlin = integral non linearity
  • peds = pedestals
  • mpd = ??
  • thold.  = threholds

These files are in $LATCalibRoot/CAL/CU06.

If you have new .xml files then the first thing to do is to copy them to that directory.

Don't have write privileges there? Then contact me or Johan Bregeon or Anders. In a hurry and none of them are available? Then try Johan Cohen-Tanugi, Joanne Bogaert, Richard Dubois.

Your next step is to enter the new files names into the RDB metadata database. If you're not in a flaming hurry, it's best to have one of us "experts" do it. 

But if we're unavailable, then log on to noric (or whatever machine your rdb MySQL system is) and type rdbGUI-new

How to find out which calibration constants were used ?

Example : CAL calib constants

Here's one way (by Dave Smith).  From the eLog, click on "list root files" to find the name of the directory on noric where the recon files are. In that directory, you can do a grep. For example,

dsmith@noric06 $ cd /nfs/farm/g/glast/u37/BeamTest06/rootData/700000698/v4r0909p2/recon

dsmith@noric06 $ grep asym *.log
recon-v1r030603p4_700000698_00000-07469.log:XmlBaseCnv           INFO successfully parsed document $(LATCalibRoot)/CAL/CU06/mc_asym.jun8th2006.CU_pass1_Pisa.xml aka /afs/slac.stanford.edu/g/glast/ground/releases/calibrations//CAL/CU06/mc_asym.jun8th2006.CU_pass1_Pisa.xml
recon-v1r030603p4_700000698_07470-14939.log:XmlBaseCnv           INFO successfully parsed document $(LATCalibRoot)/CAL/CU06/mc_asym.jun8th2006.CU_pass1_Pisa.xml aka /afs/slac.stanford.edu/g/glast/ground/releases/calibrations//CAL/CU06/mc_asym.jun8th2006.CU_pass1_Pisa.xml
recon-v1r030603p4_700000698_14940-22409.log:XmlBaseCnv           INFO successfully parsed document $(LATCalibRoot)/CAL/CU06/mc_asym.jun8th2006.CU_pass1_Pisa.xml aka /afs/slac.stanford.edu/g/glast/ground/releases/calibrations//CAL/CU06/mc_asym.jun8th2006.CU_pass1_Pisa.xml
dsmith@noric06 $

You can do the same for the other 4 types of CAL calib.xml files that are used in recon, e.g.  ci_intnonlin, peds, mpd, thold.
