FTS Report on DOY 233

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 (55054 to 55063):

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

# On DOY 222, SPC 40 HM1 (Hydrogen Maser) source changed mode and the standard dropped out of lock. HM2 was swapped in until HM1 is sufficiently stable to be put back online. 

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.
