[Isocops] IBEX Orbit# 201 ATS v002

[fair-play at comcast.net]

Nigel, 


According to the header, the per-orbit OEF file used the latest forecast STF as input. I think it should have used last month's forecast STF as input because that is what was used to generate the per-orbit STF.

The maneuver pointing values in the FORECAST STF and ATS do not match (they match the OEF). I have not seen this mismatch before. Not huge differences but the Forecast STF and ATS have always matched since I started checking the ATS. Comments, anyone?

Compare SetInrDir in ATS with pointing as defined in the Forecast STF & verify the vectors match. 
Apogee maneuver: · SetInrDir 0.984316,0.165566,0.060909 $TIME=2013/04:01:18:48:07 

· targetX: 0.98429500000000003 |targetY: 0.16568600000000000 | 
targetZ: 0.06092700000000000 

Perigee maneuver: 

· SetInrDir 0.967472,0.235916,0.091328 $TIME=2013/04:06:09:33:23
