Where can I find the most up-to-date FUSE technical information, including data for making exposure time estimates?
A. The FUSE Observer’s Guide (FOG) is the definitive source for FUSE technical information and generally contains the most recent data on FUSE throughputs, bright object limits, etc. We do not expect to make any further changes in the FOG (except to correct typos and add clarifying discussion when appropriate) until after the proposal deadline, unless important technical information becomes available that significantly impacts proposal preparation and submission. If the latter occurs, then a general announcement will be made on the GI website homepage. GIs are strongly encouraged to do all exposure time calculations with the official FUSE Exposure Time Calculator (ETC) . The ETC uses on-orbit data that accurately reflects the current instrument performance.
