[Isocops] IBEX Orbit# 137a ATS v001 - approve.

[Mark Tapley]

All,
	I have looked at the Orbit 137a ATS v001

IBEX_2011_235_o0137a_v001.txt

and I approve.

	No constraint violations.

	The PL commands in the ATS v001 match the STF v001 file

IBEX_2011_234_o0137a_v001.stf

per Ken's script (Thanks, Ken!).

	PL ascending and descending operations make sense with 
respect to 15 Re ascending, Apogee, and 15 Re descending times from

IBEX_2011_235_o0137a_v001.oef

	No Moon in -Lo FOV PMT setback commands and none needed.

	Ground station contact times match S/C commands.

	Battery cell balancing Cycle looks OK, > 1 hour from anything.

	Inertial maneuver at the end of orbit 136 left us pointing in 
a safe direction for ascending and descending macros during first 
half of orbit:

	Inertial maneuver at apogee leaves us pointing in a safe 
direction at maneuver and at following Ascending and Descending 
Macros.
