Running online analysis

(Last update 02/19/15)

  • Login as a-onl on one of the analysis machines (aonl1, aonl2 or aonl3) e.g.
 ssh a-onl@aonl2
  • passwords are written on the white board in the counting house
  • to go to the online analysis directory (/adaqfs/home/a-onl/He3H3/replay_gmp) type
 goonlana'


  • 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 < >)
