Core Minutes 12/5/2006

Present: Joanne Bogart, Anders Borgland, Toby Burnett, Jim Chiang, Richard Dubois, Dan Flath, Warren Focke, Riccardo Giannitrapani, Navid Golpayegani, Heather Kelly, Michael Kuss, Bryson Lee, Chuck Patterson, Igor Pavlin, Leon Rochester, Tracy Usher

Mission Planning: (Bryson) See his very complete write-up on design and tools, some of which was already presented at a recent Sci Ops meeting.
(Richard) What's ETA? (Bryson) will have something Steve Culp can use for testing by the end of next week. The goal is to release a production version in time for the "A day in the life.." test, now scheduled for February.

(Toby) From your description the scheme is quite generic. Have you thought about sharing with other missions? (Bryson) It's true We investigated tools used by other missions such as Gravity Probe B. They included legacy code from previous missions which would only get in our way, so it seemed best to start fresh. It could be "shared forward".

(Toby) What sort of eclipse [see p. 8 of the presentation] is being referred to? (Bryson) The standard kind: occulting of sun by earth. This is a significant in this context because we have to switch to battery power.
Onboard Filter Status: (Tracy) The gamma filter is now fully functional. He's writing an interface class, which will make it easier to add other filters. , currently making spigots for mip and heavy ion filters. From JJ: the information about filter decisions is in the filter stream, just not currently readily decodable by offline ground packages.
Inter-tower Alignment: (Michael) He is making good progress. He expects to have results by the end of the week (Thursday since Friday is a holiday in Italy).
Service Challenge:
- One-day interleave (Richard) The two kinds of background runs needed are done. Binning step is next. (Toby) Navid will write a tool to extract/generate a suitable xml file. (Richard) Tom is on vacation this week so this won't be wrapped up until next week. (Toby) Are TChains (as opposed to TTrees) needed? (Richard) Not for the one-day interleave. We will need it for February.
- Level 0 simulations Tom is putting together the level 0 pipeline definition. Anders is doing L1; see L1 processing design in Confluence.
- ObsSim runs The sun and the moon had been handled by defining a bazillion (if not more) sources which turned on and off appropriately as the objects move through the sky. Toby has now put in reference frames for sun and moon so the sourcelets are no longer needed.
- Related projects to be addressed
  - Irreducible backgrounds
  - More header info in ROOT files
- Future runs (Richard)
  - ObSim in January
  - 55-day Gleam run in February
  - 1-year science run in June
Python embedding: (Toby) has written and committed a new package, embed_python which "builds a library to facilitate embedding python" [from mainpage.h]. See Module.h for more information.
