Science Tools Working Group

Did not meet this week.

The current version of ScienceTools is still v9r1p1. HEAD1.581 (built on September 7) is also still the current release candidate. It differs from HEAD1.580 only in the GRBobs package, which now records more information about the bursts it generates; both of these have preliminary versions of the Pass 5 IRFs, as previously noted. Here are the differences between the most recent HEAD versions of the packages and the latest LATEST build.

Data products: No new news.

Databases and related utilities

No development news.

Likelihood analysis

No development news.

GRB tools

No development news.

Pulsar tools

Masa and James report that they are continuing to work on adding barycentering on-the-fly to the pulsar tools.

Observation simulation

No news. Max's feature article in this month's LAT newsletter includes a description of the inputs to PulsarSpectrum for simulating phase-dependent spectra.

User interface and infrastructure (& utilities)

From James: "James Peachey and Eric Winter began working to extend work done previously by Larry Brown to port the ScienceTools into the HEADAS build system. Specifically James attempted to use Larry's method to create a Windows distribution, starting with the external libraries. James was able to build most of the libraries, but he had problems using a more recent version of Cmake to generate working Visual Studio project files for the latest HEADAS. He is currently pursuing a work-around that will allow HEADAS to build, and will then continue with the Science Tools themselves.

James Peachey made some changes to Ape to support Visual C++ 8, then delivered version v2r2 to Navid Golpayegani for inclusion in the Science Tools external libraries."

Leftover from last week: Do we have plans to make native 64-bit builds of the Science Tools. Not that I'm aware of, but I do want to ask.

Source Catalog

Met this week. Ludovic presented more results on the improvement of source position accuracy with Toby's pointfit. Toby gave a detailed presentation of his results for finding sources in the obssim2 data set - taking into account the diffuse emission model in his analysis has markedly decreased the number of spurious sources detected. Jean presented a study of setting upper limits on expected significances of sources in the obssim2 sky model.
