FTS Report on DOY 205

I.  The following are clock offsets, in microseconds between the clocks
at each DSN complex and each complex relative to UTC(USNO).  The offset
is a mean of readings using several GPS space vehicles in common view.

III.
Comments: 
@ SPC 10 station Master Clock was reset following a planned station power outage on DOY 197 (MJD 56489). The reported time offset for DOY 197 has been computed from the average of the last 4 hours of that day. The time was shifted by about -0.35 microseconds.
# SPC 10 frequency offset was calculated from the last seven days, MJDs 56490 to 56496.

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