Science Tools Working Group

We did not meet this week and won't meet until 2008.

The current version of the Science Tools remains v9r3p4.

Data products: We discussed getting the current definitions of the data products in the File Format Document that accompanies the Interface Control Document with the GSSC that needs to be in place by the time of the Flight Operations Review. Most of our discussion was about the format of LS-003 (livetime cubes). David's draft specification needed to have a number of header keywords that are not currently included. You might also want to see Jim's note to scisoftlist, if you missed it.

Databases and related utilities

No news

Likelihood analysis

No news. Jim and Jean have been evaluating the effects on TS values from the improvement to the diffuse response calculations that Jim made and were described in last week's report

GRB tools

No news.

Pulsar tools

Masa reports that he and James have finished the first version of gtptest, the tool that runs a variety of periodicity tests for a given set of timing parameters. They have started to add support for additional binary orbit models; this will also involve extending the definition of the pulsar ephemeris database file.

Observation simulation

No news. In the LATEST build (v6r1p2 of observationsSim), Jim has shifted PHI and EARTH_AZIMUTH_ANGLE to be in the range 0-360.

User interface and infrastructure (& utilities)

Not sure where this belongs. As described in more detail in his note to scisoftlist, Toby has added the pointlike package to the Science Tools. It is both a floor wax and a dessert topping (as Heather and SNL would say). He and his students are developing it for source localization and source finding. It also sees use in their LAT-spacecraft alignment analyses and via HEALPix can make all-sky convolutions, among other capabilities.

As probably mentioned in the core report, Toby has converted the astro package to a shareable library and moved the HEALPix code to its own package (healpix).
