FTS Report on DOY 142

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 (54963 to 54972):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
^ Both SPC 10 TTR5 receivers failed since DOY 69 (MJD 54900). Data was from GPS true time with an offset. 
^ SPC 40 TTR5 receiver came back DOY 128 (MJD 54959) after station personnel recycled its power.
^ SPC 40 TTR5 receiver is on and off again after a short come back DOY 131 (MJD 54962)
& Direct subtraction was used.
# New multichannel receiver was installed at SPC 10 on DOY 134 (MJD 54965). 
# Started using common view data between SPC 10 and NIST on DOY 135 (MJD 54966). The confidence level was within 1 (ns) nanoseconds.
# There was a difference of 38 ns between data from the new receiver and the estimation using true time from the TA with an offset. 
$ There was a frequency adjustment done at SPC 10 of 5*E-13 seconds on DOY 135 (MJD 54966).
