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
Resolutions using tz=16 and Garfield for 2100V, 51Ar, 49CO2
Different scint orientations
Drift time fits, hit threshold 5#sigma
Hit threshold 6#sigma
