Re: [Brahms-dev-l] Tracking efficiency in run05 pp

Hi Pawel,

   thanks for your reply. I found in the files you
made effiencies for the 4 deg data for run05 pp. 
I have been trying to make efficiency files for 
run05 pp at 8 degrees. 

I am using gtr production 4 and some gtr DC enhancement 
offset files are missing for some of the runs. For example, 
I see

run 14351 
offset014351_seq002_seq003_seq004_seq005v0p4.off.EncT3   OK
offset014351_seq002_seq003_seq004_seq005v0p4.off.EncT5   OK

run 14322
offset014322_seq002_seq003_seq004_seq005v0p4.off.EncT3     not there
offset014322_seq002_seq003_seq004_seq005v0p4.off.EncT5

14274
*.EncT3    not there
*.EncT5    not there

I am running into problems while submitting jobs automatically.
I am not sure why these files are not generated for some runs
when the gtr files are produced.

Selemon,

I made efficiency calculation for run05_pp in August06. The maps are at 
the official
location e.g. 
/brahms/data08/corrections/trackEff/MappedEffic_run05_pp_200_PSv1.root
To check out whether the settings you need are there you can just edit 
the root file in the
root session and do >.ls, histogram's names contain information about 
the settings.

The stuff used to generate maps (../banapp/corrections/efficiency) 
includes README file
which provides step by step instruction of how to generate the maps.
Concerning variables: it is your choice which variables to map. When 
running MapEfficiency.C script (the last stage of
the process) you have to specify string VarRequested like "XAP" (Length 
has to be equal 3). In this case you will create
X vs X-slope 2D map and 3 1D maps - for X. X-slope and momentum (for 
each detector).
If  VarRequested="XPA" then the 2D map will be X vs momentum.

To use the maps ones use EfficiencyCalculator (which is fact is 
efficiency interface). EfficiencyCalculation
has setters void SetVar(TString var). if var is "XA" the 
EfficiencyCalculation will try to use 2D X vs X-slope maps.
If var is "X" or "P" it will try to use 1D X map or 1D momentum map. If 
the maps
will not be found (it refers only to particular settings) the 
calculation will inform about it and abort.

If you have more questions, then let me know.

Cheers,
Pawel.
