FTS Report on DOY 032

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:
% On DOY 030 (MJD 55956), SPC 10 online HM2 frequency was adjusted by 3.5*E-13. The time was reset to be close to NIST time.

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.
