FTS Report on DOY 183

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.

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
^ SPC 40 backup Maser (#2) was online on MJDs 54276 & 54277, during which time the prime Maser (#1) was being calibrated.
