FTS Report on DOY 169

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
$ Beginning on DOY 159 (MJD 54259) started using class 74 as common view SV between SPCs 10 and 60. 
  It appears there was a small time step at SPC 10 on DOY 160 (MJD 54260). Reason is still under investigation.
  For the same reason, report for DOY 162 could not be generated due to not having enough data points to process.
