The times of Moon angle constraints are now displayed with 1-hour resolution. For preferred TOO observations with Swift, target-Sun R.A. differences in the 0-4 hour range are now included, as well as &gt;8 hours, as per recently updated mission guidelines. ecd3addbe5b91b69099c85be564ce297 Fri, 10 Aug 2012 18:14:38 -0500 http://heasarc.gsfc.nasa.gov/Tools/Viewing.html The Viewing tool has been updated. Since RXTE has been decomissioned, support for it has been removed. Swift's orbital pole constraints and Sun angle limit have also been updated. Previous versions used the spacecraft limit of 46&deg;; this version uses the software limit of 47&deg;. bfaca85c5c53e25b3fd9598577016dee Fri, 20 Jan 2012 14:19:40 -0500 http://heasarc.gsfc.nasa.gov/Tools/Viewing.html The Viewing tool has been updated to support the upcoming mission, Astro-H. 97a4be285bf12de21141682e5e5d64a1 Tue, 19 Apr 2011 14:18:49 -0500 http://heasarc.gsfc.nasa.gov/cgi-bin/Tools/xTime/xTime.pl xTime has improved support for the Fermi mission. 2116403ed7ddba1a31d0d7d0d5d9157e Thu, 04 Feb 2010 11:42:41 -0500 http://heasarc.gsfc.nasa.gov/Tools/Viewing.html The Swift pole constraints have been updated in the Viewing tool.
