How to do a gain file...

All you need to do to create a gain file is:

  • Download script: looptestgain.C. It requires a small library created by Chad Jarvis and named checo.so. If you still had some problems with compiling probably you don't have a HTBDAQ library, which is you can get here.
  • Find calibration runs and put them into a file.It must consists of lines with run numbers and theirs number of events.
  • In root run the script. Parameters are as follow: xxx(char* input_file,char* output_file,int loops=1,int max_cycles=50000,int xtal_min=1, int xtal_max=49,int min_bin=75, int max_bin=150))
    Parameters "min_bin" and "max_bin" set the range for the gaussian fitting, which is used to find a center of a energy distribution peak.
