FTS Report on DOY 345

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 60 Prime maser was switched to the backup one on DOY 338/1723 UTC. The difference in frequency was 3*E-13 seconds.
& SPC 40 GPS receiver B was switched to GPS receiver A on DOY 344 (MJD 54079). File A contains data back to MJD 54076/1745 UTC.
