Sweet spot

TS_RunGroupC#Sweet_spot Below is the command line I used for GEMC

gemc -USE_GUI=0 -HALL_MATERIAL="Vacuum" , -N=75000 eg12_nosol1.gcard

Here is the gcard

Below is the command and the gcard used for when the solenoid was on 

gemc -USE_GUI=0 -HALL_MATERIAL="Vacuum" , -N=100000 eg12_sol1.gcard

<gcard> 

       <detector name="../../../../../clas12/fc/forwardCarriage" factory="TEXT" variation="original"/>

Raster in Z

Since the LUND files are not currently operating correctly, I will use a different method to raster in Z. I will use the GEMC command line to reduce the radius of the target to 0 cm and randomly place vertex positions along Z (like a line target). The command line for GEMC is shown below along with the gcard when the solenoid is off:

~/src/CLAS/GEMC/source/gemc -USE_GUI=0 -SPREAD_V="(0.0, 3)cm" -N=100 eg12_nosol_noLUND.gcard


<gcard> 

      <detector name="../../clas12/fc/forwardCarriage" factory="TEXT" variation="original"/>
      <detector name="../../clas12/dc/dc"            factory="TEXT" variation="ccdb"/>
      <detector name="../../clas12/ec/ec"            factory="TEXT" variation="original"/>
      <detector name="../../clas12/ctof/ctof"            factory="TEXT" variation="original"/>
      <detector name="../../clas12/ftof/ftof"            factory="TEXT" variation="java"/>
      <detector name="../../clas12/htcc/htcc"            factory="TEXT" variation="original"/>
      <detector name="../../clas12/pcal/pcal"            factory="TEXT" variation="javageom"/>

     <option name="SPREAD_P" value="4.0*GeV, 0*deg, 0*deg"/>

</gcard>

and here is the reconstruction command line ~/src/CLAS/coatjava-2.4/bin/clas12-reconstruction -i eg12_nosol_75k_noLUND.ev -config GEOM::new=true -config MAG::torus=-1.0 -config MAG::solenoid=0.0 -o eg12_nosol_75k_noLUND_rec.ev -s DCHB:DCTB:EC:FTOF:EB -config DATA::mc=true

Below are the differences between the generated and reconstructed angles for 75k events:
