FTS Report on DOY 111

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 HM1 online maser frequency was adjusted by +6.0E-13 on DOY 104 (MJD 57491).
SPC 10 related frequency offsets were calculated from DOY 105 (57492). 


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.
