First look at TOF calibration
From GlueXWiki
First Look
- first select data sample with the following conditions:
- only consider hits within 50ns of the timing peak both for ADC data and TDC data
- only consider paddles that have hits on both ends
- take care of the 6fold trigger timing shift in the TDC (24ns window)
- do a rough determination of the walk correction by using the time in the ADC as reference.
- do mean time comparison between different planes
- calculate MeanTime of Paddle i in plane j:
- calculate MeanTime for all Paddles n in plane k:
- for each event plot for each paddle in plane k:
