Science Tools Working Group

The current release of the Science Tools remains v9r15p6. Jim has made a new HEAD build and an incremental release is likely by ~Wednesday. Among other updates, it will have the P6_V8 IRFs that Toby has implemented with the in-flight PSF that he measured; this version also has the corrected fits/representation of the IRF that has been in the works for a while, dating to Matthew Kerr's study in the fall. Incorporating the P6_V8 will make them more conveniently available for further evaluation in analyses.

The development news below describes updates that are not yet in a release.

Data products: Elizabeth F.'s updated documentation of the contents of the main data products served at the FSSC (FT1, 'extended FT1', and FT2) is now available.

Likelihood analysis

From Jim:

  • Likelihood v16r2p1: Problems with the convolutions with the binned analysis (i.e., slight sub-pixel shifts of the convolved images relative to the model images) reported by Mizuno, Luigi and their colleagues have been fixed. [These issues involved subtleties of the representations of images and of the PSF. Johann has volunteered to make a write up.]

GRB tools

No news

Pulsar tools

From Masa: Nothing in the pulsar tools development. We are discussing a possibility of expanding the D4 definition to accommodate more complex radio ephemerides, but a conclusion has not yet been reached.

Observation simulation

User interface and infrastructure (& utilities)

Science Tools Working Group

The current release of the Science Tools remains v9r15p6. The development news below describes updates that are not yet in a release.

Data products: The source catalog format was updated a couple of times along the way to delivering the final form of the 1FGL catalog to the FSSC. Elizabeth F. is preparing an updated description of the contents of the main data products served at the FSSC (FT1, 'extended FT1', and FT2).

Likelihood analysis

From Jim:

  • Likelihood v16r0p0: Bug fix for resampling of model maps in binned likelihood. The modification entails enabling interpolation of the model maps when resampling using the input counts map geometry.

GRB tools

No news

Pulsar tools

Masa reports that there's no news

Observation simulation

From Jim:

  • celestialSources/genericSources v1r14p4: bug fix for half pixel offset in sampling input FITS maps SRCMOD-14@JIRA [for MapSource and MapCube sources]

User interface and infrastructure (& utilities)

From Jim:

  • dataSubselector: addressing STGEN-95@JIRA: INDEF keywords used for gtselect to allow for default behavior for the time range and acceptance cone selections. This uses changes checked in to ape 2.6 and hoops v1r1p4. Waiting for James to close the related issue STGEN-96@JIRA before resolving.
