D..4 April, 2007 (AE Version 3.135)

• Added a third stopping criterion for defining the background region in the EXTRACT_BACKGROUNDS stage (§7.13).

• To support analysis of point sources in zeroth-order HETG grating data, AE now uses the GRATING keyword in the event file to properly set the grating parameter for mkarf. I have not worked with grating data, and I am not certain that this is the only accommodation required in AE to support such analysis.
