Science Tools Working Group
We will have a short meeting tomorrow, 8-8:30 am Pacific, before the Catalog meeting.
The current release version of the Science Tools remains v9r7. Here again are the differences from v9r6p3. See the Science Tools Update for July 29 for a summary of the differences.
Jim reports that v9r7p1 will be tagged soon (building as of 7:10 am Pacific today), with a fix to gtmodel and an important update to gtmktime for analyzing pointed observations (see below)
Chris informs me that gtbin and gtbindef have been released to the world by the GSSC to support analysis of GBM data.
A tutorial on high-level analyses is most likely going to be scheduled for Monday, September 15, the day of splinter session meetings before the collaboration meeting at SLAC. Details are still TBD.
Data products: No news.
Databases and related utilities
My understanding (from Julie) is that Tom, Navid, and Tony have worked out a way for the data server at GSSC to use the authentication system at SLAC. Also, Tony is working on getting the Astro Data Server online (with some updates); in addition he plans to introduce a 'skimmer' for FT1 files. I'm not sure where it will be announced, but LAT people will get word.
Jim reports that in Science Tools v9r7p1 will add a "capability to gtmktime wherein it will compute the appropriate ROI-based zenith angle cut if the corresponding DSS keywords are present from gtselect:
ki-rh2[jchiang] gtmktime Spacecraft data file[] ../FT2_merged.fits Filter expression[IN_SAA!=T] LIVETIME>0 Apply ROI-based zenith angle cut[yes] Event data file[] events_100_300000.fits Output event file name[] foo.fits ki-rh2[jchiang]
In the above, the user has the ability to disable this. (dataSubselector v6r2)"
Likelihood analysis
Jim reports that Science Tools v9r7p1 will have "a fix for gtmodel wherein the normalization of the model maps was somewhat off from the fit result (Likelihood v13r17)"
GRB tools
No news
Pulsar tools
From Masa: "James and I went through the code to finalize our clean-up works, and ended up finding some issues and bugs (including the one reported as JIRA PULS-44). We are currently working on them."
Observation simulation
No news
User interface and infrastructure (& utilities)

Source Catalog
Met last week; see Dave's notes linked to the agenda page. The topics included (provisionally) naming ASP sources and derivation of light curves for the sources. Alignment checks in Toby's analysis were also discussed, as well as Kent's detection of sources by eye from Toby's maps.
