All,
I have looked at the Orbit 171 ATS v002
IBEX_2012_179_o0171a_v002.txt
and I approve.
Soft constraint violations per .ccvr file:
IBEX_2012_179_o0171a_v001.ccvr
as expected. Long eclipse results in low battery SOC.
The PL commands in the ATS v001 match the STF v001
IBEX_2012_179_o0171a_v002.stf
per Ken's script (thanks!), with one exception, which is the
sequenced command for dumping the SSR. This is due to the download
going through APL, which station does not support commanding;
therefore the SSR playback (and other SC related commands) must be
pre-loaded.
PL ascending and descending operations make sense with
respect to 15 Re ascending, Apogee, and 15 Re descending times from
IBEX_2012_179_o0171a_v001.oef
Star tracker outage on 7/6, no significant effect on command load.
Eclipse on 6/28, long eclipse flag set 2 hours previous.
Moon in -LO FOV Commands match .oef time for start and run 5
hours long for a 30 hour eclipse; this is normal.
Ground station contact times agree with times in
IBEX_Orbit171Contacts_v001.txt
for 4 of 5 contacts; the second contact, marked "blind Acq",
has no corresponding SC commands.
No battery cell balancing this orbit. Charge before long
eclipse should accomplish this.
Inertial maneuver at the end of orbit 170 left us pointing in
a safe direction for ascending and descending macros during first
half of orbit:

No -Lo O-mode Commands, but -Lo is doing new TOF2 commands both arcs.
No overlap to orbit 170 commands apparent by manual check;
http://ibex.unh.edu/cgi-bin/ats.cgi has not yet ingested the 171 load.
Command Approval Checklist attached.
-Hi Neg collimator voltage back to operating at nominal voltage.
