Nigel,
     The reason I picked DOY 69 was the planning period runs from 15 re Asc
to 15 re Asc of the next orbit. For this planning period, it ran from March
10 - 19.  DOY 69 is March 10, 2013.

Nigel,

The DOY in the STF filename is based on when the orbit begins.  As far as
this software is concerned, the orbit begins just after the perigee of the
previous orbit which occurs on day 68.

We have two constraints on the transition to housekeeping at perigee:

1. Transition at 14 Re.
2. Transition 1 hour before the maneuver.

Since the maneuver window opens at 14 Re + 0.5h, rule #2 above overrides
rule #1.

IBEX_2013_069_o0199a_TEST_v001.scr looks good to me. The oef looks good
too. A couple of minor notes:

The doy in the STF filename is 068 but it is 069 in the ATS filename.

"Verify with Crossing Times report that Transition to Housekeeping State
occurs at 14 Re desc." As was the case in orbit 198, Transition to
Housekeeping State occurs 30 minute before 14 Re desc rather than at 14 Re.

Nigel





      All,
         Attached are the products for Orbit 199. And again these products
      were
      generated using the 14 - 14 re times.
            Enjoy
               Tim
