Notes:
-------
(1) These are astrometric quality ( I hope!) positions measured with
the program SATREC by Rainer Kracht. The mean error in positions is
given as 5 arc seconds and magnitudes are as given by the program
but the accuracy is given as +- 0.6 magnitudes.
(2) Using Scott Campbell's latest version of SATFIT I get the following
orbit.
1 91118U 000000 07164.79241898 .00000000 00000-0 50000-4 0 08
2 91118 2.2767 323.2197 0042971 92.3922 204.0081 1.00141693 03
I suspect the actual period should be around 1.0027 but all the other
figures should be very close to the true values.
Cheers
Greg
