This is the MOSES final optical design. Begin forwarded message: From: "Roger J. Thomas, NASA/GSFC" Date: Thu Jun 20, 2002 11:02:00 AM Canada/Mountain To: kankel@icarus.physics.montana.edu Cc: THOMAS@stars.gsfc.nasa.gov, moses@mithra.physics.montana.edu Subject: MOSES Design Table Correction Charles: Oops, my previous email had the wrong signs for detector Pitch. The detector faces should be tilted slightly upwards, in the opposite sense of the grating tilt. The correct table is below. Sorry about that.
