Good work, Ed! Your obs (without the last one on 0716 and 0730, all taken six times, with 0702 just once, improve the ones for 37 and 38 orbits/14 days. The adjoining 36 and 39 orbit elsets get worse. All get a reasonable ndot2 drag, but again 37 and 38 give the most reasonable B* term. Along with your intrinsic magnitude, and the inclination, I suspect a Centaur rocket.
