FTS Report on DOY 291

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.

II.  Frequency Offsets from linear least-squares fits on time-offsets
over the period (54746 to 54755):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
& Direct subtraction between columns (SPC40-NIST) and (SPC10-NIST).
^ Number obtained from the SPC40 GPS true time, with an offset.
% There were not enough common-view SVs between SPC 60 and SPC 10, direct subtraction was used.
$ The last TTR5 receiver sent from JPL to Canberra was installed early on DOY 288 (MJD 54753/0058 UTC)
