FTS Report on DOY 217

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 (55038 to 55047):

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

# SPC 40 Time Analyzer failed, there are no log files available from MJD 55044 thru 55046. Extrapolation was used. 
  SPC 60 TA failed also. There are no TA log files from MJD 55043 thru 55046. But the TTR 5 receiver was still on, so it's of no consequence.

NOTES:	As of DOY 135 (MJD 54966) SPC 10 data are from the newly installed multichannel receiver commonview with NIST. 
	As of DOY 68 (MJD 54899) data from (SPC40-SPC10) and (SPC60-SPC10) are derived from direct subtraction.
	Between DOYs 120 and 158, SPC 40 TTR5 single-channel receiver failed intermittently. Interpolation was used. 	
	Then on DOY 158 (MJD 54989), it failed completely. Time offset has been derived at using data from the Time Analyzer.
