Adjusting Analysis Cuts in the PionLT Experiment

  • All cuts are applied on Replay ROOTfile using the "pion_prod_analysis_sw.py" script located at /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION//scripts/online_pion_physics/.
    • The "pion_prod_analysis_sw.py" script is getting cuts definitions from /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION/DB/CUTS files.
    • If someone want to change the cut parameters, he has to change cut values in related csv files located at /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION/DB/PARAM/.
      • Note: Please don't change any cuts values if you don't know about it.

RF Timing Cuts

  • If someone wants to change the RF timing cut parameters, he has to change cut values in "ALL_Kinematics_RFOffsetsTest.csv" files located at /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION/DB/PARAM/.
  • The "ALL_Kinematics_RFOffsetsTest.csv" file looks like;

  • Here "Pi" refers to pions, "K" refers to kaons and "p" refers to protons respectively.

PID

  • If someone wants to change the PID cut parameters, he has to change cut values in "PID_Parameters.csv" files located at /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION/DB/PARAM/.
  • The "PID_Parameters.csv" file looks like;

  • Here "Pi" refers to pions, "K" refers to kaons and "p" refers to protons respectively.

Acceptance

  • If someone wants to change the Acceptance cut parameters, he has to change cut values in "Acceptance_Parameters.csv" files located at /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION/DB/PARAM/.
  • The "PID_Parameters.csv" file looks like;
