[Isocops] IBEX Orbit# 126 v001 ATS - approve

[Mark Tapley]

All,
	I have looked at the Orbit 126 ATS v001 
(IBEX_2011_140_00_00_v001.scr) and I approve.

	The portentious "PL mode unknown" constraint violation 
messages appear near the beginning of the orbit, as always. I worry 
more about this now than I used to. No other violations. Ascending 
BUS and PL commands begin 3 minutes before 10 Re.

	The PL commands in the ATS v002 match the STF v001 file 
(IBEX_2011_140_23_13_v001.stf), per Ken's script (Thanks, Ken!).

	PL ascending and descending operations make sense with 
respect to 15 Re ascending and descending times respectively.

	Moon in -Lo FOV PMT setback commands are concentric with 
times in the .oef and about 1 hour inside the .oef times, as usual.

	Ground station contact times match S/C transmitter-on times 
for all 4 contacts.

	Battery cell balancing commands are in place for this 
even-numbered orbit, and are more than an hour from anything.

	Inertial sun-pointing maneuver at the end of this orbit 
leaves us pointing safe directions at conclusion of the maneuver, at 
the following ascending time, and at the descending time following 
that.
