All,
	I have looked at the Orbit 103 ATS v001 
(IBEX_2010_330_00_00_v001.scr) and I approve.

	The standard "PL mode unknown at the beginning" constraint 
violation is the only one.

	The PL commands match the STF v001 file 
(IBEX_2010_330_11_43_v001.stf) per Ken's script. PL operations all 
make sense WRT 15 Re times, ascending and descending.

	Ground station times line up nicely with the transmitter on times..

	Battery cell balancing is >1 hour from everything.

	The sun-pointing maneuver leaves us in a safe direction at 
the time of the maneuver and at succeeding ascent and descent:
