Drift times from Garfield, edited

Zoomed in at small radius

Individual fits to drift time difference [0]*radius**[1]

Fit f(r) to each curve

Fit of param 0 values

Fit of param 1 values

One fit to drift time difference

One fit f(B,r) for all curves

Max error between fitted function and time difference is 2.3ns at radius 7.6mm in 1.7T dataset
