All,
I have looked at the Orbit 186 ATS v001
IBEX_2012_316_o0186a_v001.txt
and I approve.
No constraint violations per .ccvr files:
IBEX_2012_316_o0186a_v001.ccvr
The PL commands in the ATS files match those in the STF
IBEX_2012_316_o0186a_v001.stf
per manual inspection.
PL ascending and descending operations make sense with
respect to each other and to 15 Re ascending, Apogee, and 15 Re
descending times from
IBEX_2012_316_o0186a_v001.oef
Star tracker outage during first arc first 10 hours of
science operations; should not affect ramp-up but may require
de-spinning.
No Moon in -LO FOV.
Ground station contact commands match contact times in Contacts file
IBEX_Orbit186Contacts_v001.txt
for all 3 ADD contacts. No contacts during maneuvers.
No battery cell balancing this orbit. Did so last orbit, but
skipping this orbit and will do next 2 orbits due to eclipse.
Inertial maneuver at the end of orbit 185 left us pointing in
a safe direction for ascending and descending macros during first
half of orbit:

No -Lo O-mode Commands.
No overlap to orbit 185 commands apparent by manual check or
by reference to http://ibex.unh.edu/cgi-bin/ats.cgi which shows no
commands from orbit 185 after 11:11 (all this load's commands are day
11:12 or later).
Command Approval Checklist attached.
-Hi Neg collimator back to operating at nominal voltage.
