FTS Report on DOY 067

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.

III.
Comments: * Values derived from linear least squares extrapolation or interpolation.
# SPC 10 HM1 was swapped out to do maintenance on DOY 062 (MJD 55259).The frequency change was about 2.5*E-13 seconds. 
 
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.
