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.
Adjusting Cut Parameters
- One can adjust the cut parameters as follows:
Timing Cuts
- If someone wants to change the timing cut parameters, he has to change cut values in the "ALL_Kinematics_RFOffsetsTest.csv" file 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 the "PID_Parameters.csv" file located at /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION/DB/PARAM/.
- The "PID_Parameters.csv" file looks like;
- Here "H" refers to HMS and "P" refers to SHMS respectively.
Acceptance
- If someone wants to change the Acceptance cut parameters, he has to change cut values in the "Acceptance_Parameters.csv" file located at /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION/DB/PARAM/.
- The "PID_Parameters.csv" file looks like;
- Here "H" refers to HMS and "P" refers to SHMS respectively.
Adjusting Cut Definitions
- One can change the cut definitions as follows:
Timing
- If someone wants to change the timing cut definitions, he has to change it in "coin_time.cuts" file located at /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION/DB/CUTS/general.
- The "coin_time.cuts" file looks like;
- Here "CT" refers to Coin Time and "RF" refers to Reference Time respectively.
PID
- If someone wants to change the PID cut definitions, he has to change it in "pid.cuts" file located at /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION/DB/CUTS/general.
- The "pid.cuts" file looks like;
- Here "H" refers to HMS and "P" refers to SHMS respectively.
Acceptance
- If someone wants to change the acceptance cut definitions, he has to change it in "accept.cuts" file located at /home/cdaq/hallc-online/hallc_replay_lt/UTIL_PION/DB/CUTS/general.
- The "accept.cuts" file looks like;
- Here "H" refers to HMS and "P" refers to SHMS respectively.
