FTS Report on DOY 039

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 maser HM2 frequency was adjusted by 3.5*E-13. The time offset was also reset to NIST.

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.
