FTS Report on DOY 254

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 (55075 to 55084):

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

^ On MJD 55075, the frequency at SPC 40 HM2 was adjusted by 3*E-13 and the Master Clock was advanced by 4 microseconds.

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.
