[Isocops] IBEX Orbit# 123 v001 ATS - approve

[Mark Tapley]

All,
	I have looked at the Orbit 123 ATS v001 
(IBEX_2011_118_00_00_v001.txt) 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.

	The PL commands in the ATS v001 match the STF v001 file 
(IBEX_2011_118_04_23_v001.stf), per Ken's script (Thanks, Ken!).

	PL ascending and descending operations make sense WRT 15 Re 
ascending and descending times respectively.

	No Moon in -Lo FOV PMT setback commands, agreeing with the .oef.

	Ground station contact times match S/C transmitter-on times 
for all 3 contacts.

	No battery cell balancing this odd-numbered orbit.

	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 (using 
http://ibex.unh.edu/ibexhome/doc/isoc/spice/isoc_orbits.html for the 
descending time, since no Forecast .oef).

	No more O-mode.

	No overlap with Orbit122 commands, per 
http://ibex.unh.edu/cgi-bin/ats.cgi .

	On Command Approval Checklist, I verify the following boxes:

15 Re ASC Command Check (also includes -Hi commands to go to 1800 V on CEM 4)
Moon In Lo FOV
15 Re Desc Command Check
Battery Cell Balancing
Command Constraint Violation Report
