FTS Report on DOY 257

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.

over the period (55078 to 55087):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation

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