FTS Report on DOY 029

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.

Values derived from linear least squares extrapolation or interpolation are indicated by (*) next to the time offset.

III.
Comments: * Values derived from linear least squares extrapolation or interpolation.
# Accumulated data for DOY 22 (MJD 55218) was wiped out due to receiver needed to be reset for erroneous data. 

NOTES: All DSN data are from the new multichannel receivers.
SPC 10 and SPC 60 offsets are commonviewed with NIST and with each other.
SPC 40 offsets are all-in-viewed with NIST and with SPC 10.
