hold on Pete or anyone on shift:
I think "-bm -1" is in fact correct. see the following lines in lrn.cc:
if (opt.GetValue("MagField.Epics", false))
recon.fField->SetMagnitude
(opt.GetValue("MagField.Magnitude", 1.)
* raw->epics[blast_index].value/6727.);
"-bm -1" will set opt.GetValue("MagField.Magnitude", 1.) to -1 and the
absolute value will be calculated from
raw->epics[blast_index].value/6727.)
I think Chris wrote these codes and I have sent email to him asking for
confirmation on this issue.
sorry for the confusion and let's wait for Chris' verdict.
