FTS Report on DOY 028

I.  The following are clock offsets, in microseconds between the clocks
at each DSN complex and each complex relative to UTC(NIST).  The offset
is a mean of readings using several GPS space vehicles in common view.

over the period (54849 to 54858):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
$ SPC 40 HM1 was swapped back to be prime at about DOY 20/2140 UTC. Frequency was adjusted by 4.3*E-13 seconds.
