FTS Report on DOY 315

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
% Direct subtraction was used.
$ SPC 10 TTR5 receiver/computer crashed due to lightning on DOY 305. 
^ SPC 10 accumulated data was lost. Data computed from TA GPS true time, with an offset of 9 nanoseconds.
& SPC 40 receiver incurred a 10 nanosecond step in time after it lost lock for about 1-1/2 minute on DOY 313/0129 UTC.
