FTS Report on DOY 011

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.

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

III.
Comments: # The leap second scheduled to occur on DOY 366, 2016 was not applied to the station Master Clock at SPC-10.Station time was re-synced to UTC on DOY 004, 2017 at approximately 1905Z.For DOY 001, 002, 003 and 004 up until ~1905Z, the ACTUAL station time offset at SPC-10 was 1 second plus the reported microsecond time offset. Time offsetS for DOY 004 was back-extrapolated from DOYs 005 thru 014. # SPC 10 related frequency offsets were calculated since DOY 005 (MJD 57758).

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.
