FTS Report on DOY 148

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 (54238 to 54247):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
$ Time step was introduced at SPC 10 after the receiver came back up on DOY 138 (MJD 54238).
& Frequency adjustment performed at SPC 10 on DOY 146 (MJD 54246). The difference was -6*E-13 seconds.
  SPC 10 timing came from Maser 2 between DOYs 138 and 146. 
! SPC 60 data collected from GPS receiver A starting DOY 145 (MJD 54245)
