FTS Report on DOY 091

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 (54912 to 54921):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
^ Both SPC 10 TTR5 receivers failed since DOY 69 (MJD 54900) . Data was from GPS true time with an offset.
