KAON-LT analysis instructions

Replay:

• We would like the detector check replay to be done on first 50,000 events of every run, and compare plots with the standard ones in the binder. In addition, we want physics replay to be done on every run in its entirety. K + plots such as missing mass, t, W , Q 2 and φ should be checked for anomalies. Replay instructions are on the next page.
• Keep the file standard.kinematics up to date with the spectrometer settings for every configuration, so that the physics replay generates meaningful quantities. Use the beam energy determined from the arc measurement in the file, and the spectrometer angles from the TV.

•*Shift leaders are asked to keep a running total of the number of e − K coincidence events falling within the missing mass and fiducial volume cuts set in the physics replay kumac, so that we can better estimate when to move to the next setting.
