Chelle et al,
	Thanks to Chelle for a quick and careful review.

	Version 004 attached (sigh).

	Differences from Version 3 include:

1) Changed comment (only) to reflect the correct sun-pointing 
maneuver date I used to calculate sun angles using ibex_rotate. For 
reference, the commands I used were:

ibex_rotate -o -r +95.447 -d +23.358 ibex-sun -t 2010-06-26T20:50:36.000Z

	To get the sun vector at the time of the maneuver, then

ibex_rotate -o -r +95.447 -d +23.358 ibex-sun -t 2010-07-01T14:00:00.000Z
ibex_rotate -o -r +95.447 -d +23.358 ibex-sun -t 2010-07-01T24:00:00.000Z
ibex_rotate -o -r +95.447 -d +23.358 ibex-sun -t 2010-07-03T15:00:00.000Z

	to get the sun angles, ending at 6.491 degrees.

	I cut/n/pasted the wrong date for the maneuver, but used the 
right date when I did the calculations.

Nathan, Harald, Paul,
	Approval needed at your earliest convenience. Please send to 
me and Chelle. When Chelle hears the last approval, she should 
(please) put the file onto the SFTP site for Orbital Ops use.
