[Isocops] IBEX Orbit# 134a ATS v003 - approve.

[Mark Tapley]

All,
	I have looked at the Orbit 134a ATS v003

IBEX_2011_208_o0134a_v003.txt

and I approve.

	No constraint violations, except a battery SOC warning which 
Ryan's analysis shows is overstated - operating normally through the 
eclipse should be fine.

	The PL commands in the ATS v003 match the STF v001 files

IBEX_2011_199_o0133a_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_208_o0134a_v001.oef

respectively.

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

	No ground station contact times not sent; commands in ATS 
look OK assuming the ground contact times match.

	1 Battery cell balancing Cycle at a good time, > 1 hour from anything.

	Inertial maneuver at the end of orbit 133 left us pointing in 
a safe direction for ascending and descending macros during first 
half of orbit:

	No O-mode this orbit.

	(-Lo gain test in file IBEX_2011_Orbit133_LoGainTest_v001.txt 
runs just before descending at final perigee in orbit 133 and is 
clear of other operations; commands match -Lo STF per Ken's script; 
approval sent last week as part of O133 approval and resent 
separately.)

	No overlaps to orbit 133. I have not checked 
http://ibex.unh.edu/cgi-bin/ats.cgi, however.

	No Command Approval Checklist tonight.
