Setup for Batch Job With Varying Experimental CLAS12 Quantities
Using CLAS12 isotropic distribution LUND files for LH2 and NH3 targets and varying incident electron energy.
mv LUND_Spread_LH2.LUND LH2_0Sol_n100Tor_11GeV_Phi0deg_ShieldOut.LUND
Spliting the LUND file into 38 parts of 1000 events, or 3000 lines
split -d -l 3000 -a 3 LH2_0Sol_n100Tor_11GeV_Phi0deg_ShieldOut.LUND LH2_0Sol_n100Tor_11GeV_Phi0deg_ShieldOut_
Naming these files LUND files
prename 's/(LH2_0Sol_n100Tor_11GeV_Phi0deg_ShieldOut_\d{3})/$1.LUND/' LH2_0Sol_n100Tor_11GeV_Phi0deg_ShieldOut_*
Placing each of these files into its own directory, within a directory named LH2_0Sol_p100Tor_11GeV_Phi0deg_ShieldOut
find . -name "*.LUND" -exec sh -c 'mkdir "${1%.*}" ; mv "$1" "${1%.*}" ' _ {} \;
GCard Building
A program,File:Gcard builder.C is written to install a LUND specific gcard in each directory.
Commands Building
Similarly, File:Commands builder.C is written to install a specific commands file into each directory for testing.
Batch Conditions
The batch job will need to
cd /home/lds/src/CLAS/GEMC/experiments/eg12/MolrBckGrd/DV/Isotropic_study/LH2_0Sol_n100Tor_11GeV_Phi10deg_ShieldOut
cd /LH2_0Sol_n100Tor_11GeV_Phi10deg_ShieldOut_00

The weighting found in the LUND file is applied to the scattering angle theta in the Center of Mass frame to produce the Moller Differential Cross Section. We should be able to use the information from the detector hits such as wire numbers and sectors to find a distribution of hits with respect to the scattering angle theta in the Lab Frame. The Theta distribution will need to undergo a Lorentz transformation to the Center of Mass Frame to apply the corresponding weight found in the LUND file.
Plotting detector grids
Using ~/src/CLAS/coatjava-2.4/bin/evio-dump -i LH2_0Sol_n100Tor_11GeV_Phi10deg_ShieldOut_00/LH2_0Sol_n100Tor_11GeV_Phi10deg_ShieldOut_00.evio, we can test for the first particle hits. We show 9 hits, all on wire 1.
