Julie McEnery, Leon Rochester, Sean Robinson, Alex Schlessinger, Traudl Hansl-Kozenecka,
Tracy Usher
With Richard on a plane, Toby in a car, Joanne preparing to leave Italy, Dan
at GSFC...the rest of us attempt to carry on...
- ACD volume identifier issue
When attempting to reprocess the GlastRelease v3r3p4 runs - it was
discovered that when re-running AcdRecon, we received warning messages about
volume ids that could not be found. It turns out the trouble is due to
the bottom row of tiles - Joanne has found and corrected the error.
- Runs
A new set of AllGamma and backgndavg runs using GlastRelease
v3r3p4 with AnalysisNtuple v1r8 and TkrRecon v8r11p4 have been
started. Stay tuned to:

- New Gaudi Root Persistency Service
Ursula reported on her status with the new ROOT persistency service.
She has the beginnings of a service and desires to test a single converter
that will extract a single item from the TDS and output it to ROOT.
The appropriate combination jobOptions has not yet been found and Ursula
asks for any tips that we may have. A message has been sent to Toby,
Joanne and Heather - Heather will take a look later today.
- TKR-Land
Toby, Leon, and Bill have fixed up some bugs - including the seemingly
random crashes due to negative energy calculations.
Leon has been busy working ToT issues. Bill has started looking at
using ToT as a means to cut upward moving protons. Apparently in
reality, the ToT saturates at 5 times a MIP (minimum ionizing particle),
which impacts its effectiveness on protons and CNO. The Monte Carlo
was not saturating the ToT. This has been fixed at the HEAD of TkrDigi.
In the meantime, thet variables in AnalysisTuple are calculated in a kludgey
way to cause saturation. In testing this, Leon is working to revive
histogram creation in Gleam.
Tracy finished 7th or 8th in the World Championship Laser Masters Class -
and we're proud to have him back in GLAST-land
- CAL-Land
Berrie is
re-writing the documentation for that part of CalRecon he's been involved
in. He's also interested in G4Propagator and may contact Tracy/Leon
for more information. Leon pointed out that CalValTools in
AnalysisNtuple may be doing precisely what's he's interested in. (yes, nice
and vague...blame the minutes-writer..Berrie provided a very nice and
detailed explanation and this is what came out the other
end..)
- DC1 Status
- Root => FT1
We did indeed have our meeting last Wednesday and as a result, for DC1,
Jim Chiang will continue working on rootTuple to provide the mechanism
to convert from the merit ROOT ntuple into FT1. Toby has continued
to work on updating merit - including providing a new exposure
tree. In addition, discussion continues to hammer out a final FT1
format for DC1.
- OnboardFilter
Navid reported that JJ approved modifications have been made to the
filter as a result of David Wren's work.
- gcc 3.2 and Redhat 9
Alex reported that he has the set of external libraries that Johann
provided for Redhat 9, and will make them available. In addition,
Alex will continue working on turning on the optimization for the Linux
builds.
- OPUS - no new news
- Action Items: not reviewed.
- Document effect of MC pruning options (Riccardo) (8/5/2003) It's
documented in the code; Tracy will look into putting the information in a
more accessible place. (9/2/2003)
- Reorganize RootAnalysis package so structure is more standard.(05/13/03)
- Write up, and perhaps present at a future meeting, hints on debugging.
(02/18/03) Linux document
exists, needs to be linked in somewhere.
Some combination of Toby and Tracy will provide something for Windows.(7/22/03)
- Overhaul documentation altogether by about November (Heather and ??) (9/2/2003)
- Resolve calibration/timestamp issue. (11/20/02) Online folk have not yet thought about
putting timestamp information into EM data, but, thanks to Richard's
inquiry, may now do so. (2/25/03) We can probably live without a realistic
system for EM, but we will put it on the agenda for the DC1
workshop.(5/6/03) At the DC1 Workshop Steve Ritz promised to find an
authoritative reference for timestamp format and pass it on. (7/17/03) Now
that events have "real" timestamps, Joanne needs to reassess
situation with Calibration (9/2/2003)
- We need a web page on the workings of the Release Manager
(5/6/03) In progress (Navid) (9/2/2003)
