Likelihood analysis
From Jim:
- I re-implemented the BandFunction available for Likelihood analyses in order to allow users to specify the energy scale for evaluating the power-law parts of that function (J. Ballet request). The workbook documentation has been updated (Likelihood v14r8)
- I modified gtfindsrc, gttsmap, the TS calculation in gtlike and pyLikelihood, and the upper limits calculation in pyLikelihood to use the new function in the optimizers package, Optimizer::find_min_only (in optimizers v2r15p9), which skips the covariance matrix calculation at the best-fit location. This should speed up the execution of these tools [possibly by a factor of a few]. (Likelihood v14r9, pyLikelihood v1r12p2)
- The error radius returned by gtfindsrc now includes the 1.51 factor derived by Juergen. This means that the reported value can be directly interpreted as 68% containment radius.

Masa reports that he is continuing to work on improving the unit tests for the pulsar tools
Observation simulation
From Jim: "I modified the Isotropic source used in gtobssim to model the extragalactic diffuse component. Users can now specify a cone on the sky over which the incident photons will be generated. Here is an example xml definition:
<source name="Extragalactic_diffuse_20">
<spectrum escale="MeV">
<SpectrumClass name="Isotropic" params="flux=10.7,gamma=2.1,emin=20.,emax=2e5,ra=0,dec=0,radius=20"/>
<use_spectrum frame="galaxy"/>
</spectrum>
</source>
