Drift time fit
Estimate of t0 is 850.09 and tmax is 1464.19, difference is 614.10
Straight-line intercept is 834.51, to match histogram fit t0, use tz_add 15.58
Drift time vs channel number, threshold 5#sigma
|
Drift time vs channel number, threshold 5#sigma and amplitude>180
|
Number of hits which were not on the fitted track
|
Off-track hits vs total hits
|
Event 23, 4 hits off-track
|
Event 253, 48 hits off-track
|
Event 1037, 21 hits off-track
|
Resolutions using tz=16 and Garfield for 2100V, 51Ar, 49CO2
Resolution, ALL CHANNELS, violet=total hits<24, dk blue: 5 or less hits off track
