FTS Report on DOY 164

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 (54254 to 54263):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
^ There were not enough common-view SV between SPCs 10 and 60 on DOYs 153, 155, and 156 (MJDs 54253, 54255, 54256)
! Started getting SPC 60 data from GPS receiver B on DOY 155 (MJD 54255).
$ Beginning on DOY 159 (MJD 54259) started using class 74 as common view SVs between SPCs 10 and 60. 
  A small time step appears at SPC 10 on DOY 160 (MJD 54260) due to the switch of class SVs.
  Also for the same reason, report for DOY 162 could not be generated due to not having enough data points to process.
