... rgsfilter creates the filtered event list as an exact replica of the combined event list, then removes unwanted frames and events, and adds the node-specific exposure maps. ... The common practice of including the effective area in the exposure map is rejected because the effective area is handled more correctly by including it in the response matrix. ... The combined map covers the full channel space, so that channel numbers assigned to the events are coordinates in this map. ...

Date: Sun, 28 Sep 2008 18:31:24 -0400 From: Rodger Doxsey Subject: HST safing last night Last night, the NSSC-I, and all the Instruments, were placed into safemode by the 486 (spacecraft) computer. ... At this point, it seems the problem is in the hardware located in a unit called the CU/SDF (Command unit/Science data formatter I believe). This unit is associated with the NSSC-I, and handles commands and telemetry functions between the NSSC-I and the instruments and the 486. ...
