Would someone be so kind as to tell me if the OMS-2 TLEs from Ted's
message (below) are good (enough) for the first several orbits?  I would
guess these are post-OMS-2, presumably meaning they're good until the
next orbital maneuver.  But since that's just a guess, I would
appreciate being enlightened.  Thanks.
