Science Tools Working Group
We did not meet this week.
The current version of ScienceTools is still v9r1p1, and with HEAD1.580 remains poised for the next release.
Data products: No new news.
Databases and related utilities
No development news.
Likelihood analysis
- bug-fixes
- gtmodel now correctly produces output maps with image datatypes of float when the input counts cube map has datatype of integer (LK-35)
- The NewMinuit interface to the C++ version of Minuit did not account for parameter name collisions for spectral components from different sources. This is now fixed in optimizers v2r11.
- new functionality
- The best-fit parameters that have been found are stored so that when optimizers exit with an exception, thereby often leaving the parameters at a non-optimal set, the user now has the option of restoring the best fit values that have been found so far. This is available in pyLikelihood v1r1p2.
GRB tools
No development news.
Pulsar tools
No development news.
Observation simulation
- bug-fixes
- Toby modified the SimpleSpectrum source in the flux package so that it can model sources with photon spectral indices of exactly zero.
User interface and infrastructure (& utilities)
No news.
Source Catalog
Met briefly this week. Jean posted some updates to his investigations of the TS, Flux and spectral index distributions produced by Likelihood fits of the obssim2 data.
