BCAL hadronic efficiencies
Description of Method
The code is located on Github. The user will be mainly interested in the scripts contained in the folder ROOT_macros
Steps to extract the BCAL Hadronic Efficiencies:
0. Generate the root trees using the BCAL_Hadronic_Eff plugin. This is usually completed as part of the routine GlueX monitoring launches.
The output trees are located in files such as /cache/halld/offline_monitoring/RunPeriod-2019-11/ver12/tree_bcal_hadronic_eff/merged/tree_*.root
1. Run python script Read_bcal_hadronic_eff2.py. Edit the file as needed to point to the correct directories.
Create directories with the names of 'root', 'dat' and 'pdf' This script iteratively executes the Read_bcal_hadronic_eff2.C script on each of the root trees. The ROOT output files will be placed in the 'root/' subdirectory. Summaries of the efficiencies are stored in the 'dat/' subdirectory. These will be used later for plotting summaries Output plots with details of the efficiency systematics are placed in the 'pdf/' subdirectory. These can be checked for problem.
2. Run python script plot_bcal_hadronic_eff.py. Edit the file as needed to point to the correct directories.
The output of this script is just a file called plot_bcal_hadronic_eff.list, which contains the list of run numbers obtained from the 'dat' subdirectory.
3. Run the ROOT script plot_bcal_hadronic_eff.C, Edit as needed to produce useful output.
The output of this script is the file bcal_hadronic_eff.pdf file with various plots of efficiency vs run number.
