Analysis Launch Plugin Requirements

To make sure everything works, and to save memory and speed up the analyses, the following restrictions are placed:

General Requirements:

• Plugins must be checked into your home area in: https://halldsvn.jlab.org/repos/trunk/home/
• Plugins and DReactions must have unique names: No one else can use the same names (we can't run 4 plugins named "omega"), so try to do something unique (e.g. "omega_pmatt").

Memory Requirements

• Maximum of 10 DReactions per user.
• Don’t use a ton of memory (e.g. many DHistogramActions).

Cut Requirements

• All analyses (i.e. DReactions) must use an EventStore skim.
  • Available_EventStore_skims
• All channels must have at least the following cuts:
  • Pre-combo loose mass cuts around peak
  • Loose PID cuts (each particle & detector)
  • Kinematic fit converges (if any).
• These cuts must be placed before the kinematic fit is performed (except kinfit confidence level, of course).
  • The kinematic fit is performed as soon as the fit results (e.g. 4-vectors, confidence level, etc.) are requested.

Recommended Loose PID cuts

• Proton:
  • TOF: +/- 2.5 ns
  • BCAL: +/- 2.5 ns
  • FCAL: +/- 3 ns
• π+, π-:
  • TOF: +/- 2 ns
  • BCAL: +/- 2.5 ns
  • FCAL: +/- 3 ns
• K+, K-:
  • TOF: +/- 0.75 ns
  • BCAL: +/- 2.5 ns
  • FCAL: +/- 3 ns
• γ:
  • BCAL: +/- 3 ns
  • FCAL: +/- 5 ns
