Hi,
the hydrogen v3_4_18 recrunch is complete.
Major difference to v3_4_17 is that the holding field has been turned on
for reconstruction, and the bugfix in pathlength.
Eugene, please evaluate kinematic corrections for v3_4_18 (and v3_4_17!)
while separately accounting for proton eloss and send the parametrizations
to blast_anaware.
How much has the coplanarity peak changed compared to v3_4_17?
Yuan, please look at the pathlength variables, both the original ones and the
recently added ones.
Regards,
Michael
