Digitization and Resolution in 2DH after current fix

The plot below shows the x-position (upper pannel) and y-position (lower panel) of hits found by 2DH after the fix being discussed. There is still digitization in both coordinates, but it is much improved in y, and a little in x. For reference, the red lines indicate the size of one pad (for x plot) or one bucket (for y plot).

The next plot shows the distribution of residuals for x and y.
(The number of entries in the x-plot is lower because I had to make a cut such that |x|<1 cm. The reason is that BTF sometimes makes xdev_fit on the order of meters!!!)
