D..9 August, 2006 (AE Version 3.100)

• Facilities have been developed to help the observer conduct a source-by-source review of multiple spectral models produced by multiple sessions of the FIT_SPECTRA stage. The observer is shown the fits results (parameter values, luminosities, and spectral plots) for all the models available for a given source, and the observer is able to designate the preferred model. See §7.20 and §7.19.

• The TARA package now includes a tool (match_xy.pro) to match catalogs using positional uncertainties for individual sources and a match significance threshold, rather than using a fixed matching radius as is commonly employed. This tool can be used to match catalogs from different observatories, or can be used to find the intersection of Chandra source lists obtained from multiple source detection runs. (See §10 of the TARA User's Guide)

• Our two-temperature thermal plasma fitting script, wabs_2apec.xcm, has been updated to work with the current version of AE.

• AE's behavior when the MODEL_CHANGES_FILENAME parameter is provided to the FIT_SPECTRA stage (§7.18) has changed slightly.

• Keyword OBS_REGION_FILENAME added to EXTRACT_BACKGROUNDS stage (§7.13).
