Instructions for running online analysis:

  • Login as a-onl on one of the analysis machines (aonl1, aonl2 or aonl3) Eg: "ssh a-onl@aonl2"
  • passwords are written on the white board in the counting house
  • type "goonlana" - this will take you to the online analysis directory (/adaqfs/home/a-onl/gmp/replay)


  • To replay a LHRS run:
    • type "analyzer"
    • at the prompt, type ".x replay_L.C(run_number)" (provide run_number you want to replay, for left arm it is < 20000)
    • answer any questions, if needed
    • exit analyzer by doing ".q"


  • To replay a RHRS run:
    • at the prompt, type ".x replay_R.C(run_number)" (provide run_number you want to replay, for right arm it is >= 20000)
    • answer any questions, if needed
    • exit analyzer by doing ".q"


  • How to look at the online histograms?
    • For LHRS, do "onlineLHRS <run_number>" at the terminal (without < >)
    • For RHRS, do "onlineRHRS <run_number>" at the terminal (without < >)
