Hit fraction with 1d/2d and jtf/btf

Here, we have the number of hits reconstructed on the track (TRKS.NHITS) divided by the number of padrows that the track should have crossed inside of the TPC. This is filled in the field TRKS.FRAC_SEEN.

It is seen that using the 2d hitfinder (instead of 1d) and/or using btf (instead of jtf) improves (i.e. increases) this number.

Here are the averages for eight 6 GeV events. Click on the number to see the distribution.
