All,
I have looked at the TEST ONLY Orbit 198 ATS v002
IBEX_2013_060_o0198a_TEST_v002.txt
and I approve.
Only one constraint violation per .ccvr file:
IBEX_2013_060_o0198a_TEST_v002.ccvr
which is probably related to the changeover from Re-10 to
Re-14 orbit delineators.
The PL commands in the ATS v002 file match those in the STF
TEST_IBEX_2013_060_o0198a_v001.stf (name possibly not correct)
according to Ken's script (thanks!).
PL ascending and descending operations make sense with
respect to each other and to 14 and 15 Re ascending, Apogee, and 15
Re descending times from
IBEX_2011_060_o198a_TEST_v002_.oef
and
IBEX_CrossingTimes_2013_045_12_32_v001.txt
Star tracker outage for 3 days and 7 hours of second arc
science operations; may require de-spinning but occurs after inertial
maneuver at apogee is complete.
Moon in -LO FOV during descending arc; ATS commands are 0.5
hours early start and 4 hours early end compared to .oef start and
end times for a 17 hour Moon in FOV period, which is about normal.
No Ground station contact commands nor Contacts file.
No Battery cell balancing this orbit.
Inertial maneuver at the end of orbit 197 not specified.
Inertial maneuver at apogee leaves us pointing in a safe
direction at maneuver and at following Ascending and Descending
Macros.

No -Lo O-mode Commands.
No overlap to any previous commands apparent by manual check;
http://ibex.unh.edu/cgi-bin/ats.cgi has not yet ingested the o198
test load.
Command Approval Checklist attached.
-Hi Neg collimator back to operating at nominal voltage.
Pointing for -Lo ISM mode operations during January complete,
so sun angles are back to normal.
