Note on the procedures how the calibration constants are determined from
 the sample data taken at the beginning of the run.

This note instructs how to obtain the necessary parameters for the 
online data taking for RHIC pC polarimeters and how to generate those
files with half-automatically. The description here is valid for the 
data in Run-04 and might be obsolete in Run-05 new data format.

The base directory is assumed to be 

     pc2pc.rhic.bnl.gov:/home/e950/pol2004-offl/Macro

in the following explanations.

(1) Dead layer estimation 

    [1] need to create the histograms (TOF vs. Edeposit)
        use script "dlayergen.pl"
  
        > ./dlayergen.pl <RUN NUMBER>   ex. <RUN NUMBER>=3615.003

        this will create the root format file in ./Douts directory
        ./Douts/<RUN NUMBER>.root        

    [2] use script "dlayercal.pl" to fit with two parameters 
        (Dlayer, T0) 
   
        > ./dlayercal.pl <RUN NUMBER> <BEAM ENERGY>
        if the values are correct, then type "y"
  
       after some time, the new files are generated 
        - Dlayer/<RUNNUMBER>.fittemp.ps      ... fit of 2D each strip 
        - Dlayer/<RUNNUMBER>.summarytemp.ps  ... summary of all strips
        - Dlayer/<RUNNUMBER>.temp.dat        ...  
          
          1st raw -- Strip
          2nd raw -- dlayer (ug/cm2)  for detector
          3rd raw -- Tzero   (ns)     for fixed dlayer  
          4th raw -- Tzero error
          5th raw -- dlayer           for strip
          6th raw -- dlayer error     for strip
          7th raw -- Tzero            for strip
          8th raw -- Tzero error      for strip
          9th raw -- Reduced Chi Square 
	 10th raw -- NDF
         11th raw -- Fit Status
	 
	 12th raw -- Const
         13th raw -- Slope
         14th raw -- coef(0)
         15th raw -- coef(1)
         16th raw -- coef(2)
         17th raw -- coef(3)
	 18th raw -- coef(4)
 
(2) Energy calibration (Am)

 
    [1] need to create the histograms (ADC spectrums) 
        use script "calibgen.pl"
    
        > ./calibgen.pl <calib data>     ex. <calib data>=004_b 
                                             if the data file is 004_b.dat

        this will create the root format file in ./Douts directory
        i.e. ./Douts/<calib data>.calib.root

    [2] use script "calibcal.pl" to fit with gaussian

        > ./calibcal.pl <calib data>
        new file will be created in ./Calib directory
	    <calib data>.fit.log
	    <calib data>.fittemp.ps          ... strip by strip
	    <calib data>.summarytemp.ps      ... whole strips
	    <calib data>.fittemp.dat         ... the result ascii 
           
            1st, 2nd raws are strip number (0-71) and Energy Coefficient
            Others are less important
          
(3) Integral vs. Amplitude Correlations
    [1] the converted files are already made at (1)[1] with dlayer

    [2] use script "integcal.pl" to fit with linear function
   
        > ./integcal.pl <integ data>            ex. <integ data>=3615.003

        the new files will be created in ./Integ directory
	    <integ data>.fit.log
	    <integ data>.fittemp.ps          ... strip by strip
	    <integ data>.summarytemp.ps      ... whole strips
	    <integ data>.fittemp.dat         ... the result ascii 

            1st ... strip number (0-71)
	    2nd ... A0
	    3rd ... A1
            4th ... A0E
            5th ... A1E 

            Integ (0-4000) = A0 + A1 * Amp (0-250)

(4) Convine above results into one parameter file

             Check and Modify the script "ParamConvine.pl" for used 
             parameter files in it.

             ./ParamConvine.pl

              this will create the convined file "config.dat"
