FTS Report on DOY 163

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 (54618 to 54627):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
^ Number obtained from the SPC40 GPS true time.
& Direct subtraction between columns (SPC40-NIST) and (SPC10-NIST).
^$ On DOY 154 (MJD 54619) SPC 40 Master Clock was reset due to Station power upgrade and faulty wiring problems. A different offset is used.
