LISTSERV 16.5 - HPS-SOFTWARE Archives

Dear Colleagues,

I've added a few plots from my analysis of the tpass7d FEE skim from run 5772 to the Slack channel https://heavyphotonsearch.slack.com/messages/C5FCT7161/

Looking at 6-hit tracks, the mean momentum scales of top and bottom are within 1% of each other, with momentum resolutions of roughly 6.6% (top) and 7.2% (bottom). This should be taken with a grain of salt, as the backgrounds could be reduced and the functional form of the fit should be improved (simple double Gaussian at the moment).

Again, the fact that the individual track momenta are slightly low, and the Møller mass is slightly high points to some future gains to be had from improved calibration/alignment.

Enjoy the weekend,

Norman

Hi All,

new tpass7d is processed, which included
most of the fixes, except the "Large dphi"

No "Singular Matrix" exception is observed in this pass.

Instead One new exception types are observed
"BorderedBandMatrix decomposeBand not positive definite", however only
for 1 file

Also for some reason sever cached evio files had file size 0, and
consequently no reconstruction started on these files.
I did a ccpr on this.

Details are summarized in the confluence page:
https://confluence.slac.stanford.edu/display/hpsg/tpass7d

ONE thing that will be highly desirable for future debugging, is to printout
time information in a Human readable format, currently
it prints 19 digit time like this below. Is anyone know how this can be
done?
