Re: Problem with FDC hits in new savehits.F
Hi Richard,
I believe I have found the error. After verifying that the problem
persisted using a fresh build on both OS X 10.5 and Linux F8, I noticed
that the hddsGeant3.F file in the HDGeant directory was not consistent
with the XML in the hdds directory. Specifically, the change made on
Jan. 3 (revision 4652) changed the FDC wires to be insensitive. I'm not
sure how this leads to such a dramatic change, but it sure seems to. I
tried remaking the hddsGeant3.F file from the XML and now I see lots of
hits in the first event. When I change that FDAW volume's "sensitive"
attribute to "true", I get only a couple of hits.
I have now committed an updated version of the hddsGeant3.F file to
the release-2009-01-06 since that was broken as it was. For the future
we will change the Makefile in the hdds directory to automatically place
the hddsGeant3.F file in the HDGeant directory and we will remove the
hddsGeant3.F file from the repository altogether to force regeneration.
Regards,
-David
