FTS Report on DOY 087

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 10 switched to GPS receiver A on DOY 86 (MJD 54186)
$ NBH receiver down early on DOY 86 (MJD 54186). Extrapolation used.
