[Isocops] IBEX Orbit# 201 ATS v002

According to the headers in the oefs, both version 1 and version 2 used the TEST forecast STF (IBEX_2013_forecast_04mar13-22may13_test_v002.stf) as input !!! The test files should only be in the test environment.

The maneuver targets do indeed match the targets in the test oef.

2013-04-01T18:50:07.000Z,ManeuverWindowStart,targetX:0.984316,mvrDuration:900,targetZ:0.060909,targetY:0.165566,orbit:201
2013-04-06T09:35:23.000Z,ManeuverWindowStart,targetX:0.967472,mvrDuration:900,targetZ:0.091328,targetY:0.235916,orbit:201

Sorry guys, we need to produce v003.

> 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?
