Science Tools Working Group

We did not meet this week and will not meet next week either. Best guess is June 28 for the next Science Tools meeting.

The current version of the Science Tools is v7r3; Jim tagged this last week, at the end of build cycle 18. 'DC2 installers' for this version are not (yet) available. Navid has not been asked to make them, and I think that we may want to be selective in which versions we ask him to build, at least until the system for making distributions for the various supported platforms is automated. Here's what's new since v7r2; the ScienceTools package release.notes have a concise summary of the new features.

Databases and related utilities

No news.

Likelihood analysis

From Jim: "I re-activated the counts spectrum plotting option for gtlikelihood and discussed further development of the option with James Peachey and Analia Cillis; I fixed a bug in the xml output for the FileFunction source in Likelihood, and modified the interface in the optimizers package so that the C++ version of the Minuit libraries that are shipped with ROOT can be used by Likelihood."

GRB tools

No news.

Pulsar tools

Masa and James are working on the TimeRep class that will implement the conversions between representations of time - like MET, MJD, etc.

Observation simulation

Jim has reimplemented the FileSpectrum source - which allows an arbitrary spectrum for a point source to be specified as an ASCII table. The concept has not changed, but the implementation is more robust.

Max has enhanced PulsarSpectrum (to v1r2) to allow an arbitrary phase dependence for pulsar spectra. This is an important advance. Right now, I don't know how the user specifies the inputs, but the new version appears to be part of v7r3 of the ScienceTools, so it is certainly available for playing with. Max reports that a small update to v1r2p0 is in the works.

User interface and infrastructure

No new news. James reports that he is doing some more work on APE, the replacement for PIL in HEADAS. I have not worked myself up to asking what APE stands for, partially out of fear that it stands for A PIL Enhancement.

Source Catalog

The catalog group did not meet this week.
