Hi Felix,

Actually, it was a numerical protection that we built in quite some time ago and that has been removed without my knowledge. There also have been some other improvements in the code.
|
Do you mean the protection against low momenta? I removed it some months ago since we fixed the realated problem in GEANE (or at lest I thought it was fixed...). I am really sorry if this is the cause of the crash, but I really cannot understand why GEANE started to crash again on low momenta after several months of good work.
After next week I will investigate GEANE in more detail and make a full check, sorry for not beeing able to do it now.
Unfortunately there is also a bad news. With the updated code I get this crash:
Found Tracks: 1 in event no. 264

*** Break *** floating point exception

There was a crash (kSigFloatingException).

when running the Kalman...
However if I use an older revision it works... I saw it on a run of low momentum single track muons and one of electrons (below 1 GeV/c).
...I hope this will not affect channel reconstruction...
