FTS Report on DOY 071

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.

Comments: * Values derived from linear least squares extrapolation or interpolation.
# SPC 10 HM1 was swapped out with HM2 for maintenance. This is to fill the hydrogen bottle while it's off line.

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.
