Science Tools Working Group

We did not meet this week and we won't meet next week either.

The current version of ScienceTools remains v9r1p1, although since last week we have a new release candidate (HEAD1.578). Among the differences are that the release candidate include's Jim's initial implementation of the Pass5 IRFs, in Diffuse, Transient, and Source versions. Again, Jim has posted some details of the definition.

From Chris regarding plans for the next 'beta test' by the GUG:

  • Plans for a targeted beta-release of the SAE were discussed in a GSSC-LAT telecon. The time frame for the release is week 2 of Decmber 2007.
  • The hmake build/install system will be implemented as part of the beta release, so beta testers will have the option of building from source, or installing platform-specific binaries.
  • The pool of beta testers will be derived from both the GLAST Users Group and the LAT and GBM teams. A deadline for final feedback to the GSSC will be about 5 weeks subsequent to the release which will allow >6-months implementing changes for the first public SAE release at about mid-Cycle 1.

From James, regarding Masa and his work on barycentering-on-the-fly: "This requires careful consideration in order to allow an intuitive way for users to control the new functionality, while minimizing complications for non-expert users. Also there is potential for confusion because some combinations of parameter inputs may not be valid. For example, users will need to supply RA and DEC only when barycentering, but whether barycentering on-the-fly is needs to be performed is not in general known at the time the parameters are obtained."

Observation simulation

No news. The desirability of giving each source a unique MC_SRC_ID was discussed briefly in the Service Challenge Steering meeting on Wednesday. The faint blazars in the current sky model are implemented as a population (>5000 sources) with only one MC_SRC_ID between them. This is convenient for generating definitions and much faster for generating data, but has disadvantages when you want to compare the 'truth' to catalog results.

User interface and infrastructure (& utilities)

No news.

Source Catalog

Did not meet this week. Jean has posted some new results on the obssim2 catalog and on interpretation of TS, in advance of next week's meeting.
