Jim fixed a bug in the FileSpectrum and FileSpectrumMap sources source (that also affects FileSpectrumMap and RadialSource) regarding how the energies of generated photons are assigned. The bug had gone unnoticed since v7 of the Science Tools; the effect was fairly unsubtle but these sources have not been widely used in the sky models.

For the Beta Test the GLAST Users Group members will be working from their home institutions, i.e., without direct hand holding from the GSSC. As reported last week, Analia Cillis at the GSSC has updated and extended the reference pages for the Science Tools. These will be made available in the User Workbook. She is also working on updating the tutorials.
Source Catalog
Met last week. Ludovic reported on improving the sensitivity of MR_filter for source detection. Jean reported further results on catalog analysis of time intervals containing pointed observations using the 55-day LEO data set and on the effects of bright, non-power-law sources on results for their surroundings. The former is an example of a strategy for analysis when the residual background cannot be considered negligible. Tyrel gave an update on his work to study the use of covariance information from Recon for improving the accuracy of source position assignments.
