Science Tools Working Group

Our last meeting was January 16. We probably will meet this week on Wednesday (tomorrow).

The current version of the Science Tools remains v9r4p1.

Data products: No news as of this writing regarding the status of demonstrating to everyone's happiness the delivery of LS-001, LS-002, and LS-005 data products from the L1 pipeline to the GSSC.

Databases and related utilities

No news

Likelihood analysis

Jim resolved JIRA issue LK-40, responding to David Landriu's observation that changes to the selected optimizer in pyLikelihood was not updated in the information that is printed about the state of the program.

GRB tools

No news

Pulsar tools

Masa reports that he and James are continuing to work on implementing handling of ephemeris handling for alternate sets of timing parameters for binary pulsars.

Observation simulation

No news. The GSSC has asked, and Jim has agreed, that gttakosim be renamed gtorbsim in future releases. You may recall that the old gtorbsim is no longer being built anyway.

User interface and infrastructure (& utilities)

Not sure where this belongs, but Eric Winter reports that he has successfully ported v9r4p1 of the Science Tools to the HEASARC hmake environment. This built on his experience with doing the same for v9r2p2 and what could be reused was reused. I suspect that it was a complete port; for distribution to end users in real life (as opposed to GLAST Users Group beta testers), I think that the test applications and assorted other applications like makeFT* will be removed.

For the beta test by the GUG, Eric reports that he is likely to get back to making an extended version of ModelEditor that (to the extent possible) can translate between likelihood and obsSim source models and also will use ROOT GUIs.

I have heard that Analia finished making extended reference pages (equivalent to FTOOLS fhelp pages) for the Science Tools. These have been mostly reviewed by the tool developers and should be provided to Chuck soon. Analia may also start bringing the Workbook tutorials up to date.

Source Catalog

Met last week. Jean presented initial results from studying the effect of bright sources on source detection and characterization in their vicinities. The concern was that the bright EGRET pulsars especially are not well fit by the unbroken power-law spectra that are assumed for the Catalog analysis. Jean-Marc's investigations of the residual charged-particle backgrounds in the LEO 55-day data set were also discussed.
