[Isocops] Fwd: STF for Orbit 0101 - v003 done.

	the .v001.stf for orbit 110 has been modified to include -Lo 
O-mode commands, and to terminate O-mode and all science operations 
early, and to exclude the no longer needed Moon in FOV commands, 


	which is attached, and has been copied from my directory on 
ena.unh.edu to:


	it has also been placed on the SFTP server at:


	Changes include:

1) Added Lo O-mode commands from oxymode_o0110_v1.stf

2) Made the O-mode end commands happen 11 hours earlier, leaving 30 minutes
	before start of the Descending macros

3) Commented out the Moon-in-FOV commands (because they would have taken place
	after the Descending macros began)

4) Made the Descending macros happen 13 hours 30 minutes earlier.

	Descent is now complete by 2011-01-25T10:32:44.000Z, which is 
very close to the last "safe" time according to the ibex_rotate 
analysis of the sun-pointing angle resulting from the sun-pointing 
maneuver at the end of Orbit 109:

	It would be great if y'all could go over this with a 
fine-tooth comb. I have already found and eradicated several nasty 
arithmetic errors.

	the above comment notwithstanding, I think this is ready to 
go for the ATS.
