FTS Report on DOY 317

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.

II.  Frequency Offsets from linear least-squares fits on time-offsets
over the period (55138 to 55147):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
# Values derived from interpolation due to SPC 60 receiver failure on MJD 55141

NOTES:	As of DOY 135 (MJD 54966) SPC 10 data are from the newly installed multichannel receiver commonviewed with NIST. 
	As of DOY 212 (MJD 55043) SPC 40 data are from the newly installed multichannel receiver all-in-viewed with NIST and with SPC 10.
