FTS Report on DOY 131

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.

Comments: 
On DOY 357 (MJD 55553), SPC 40 HM2 (the new Symmetricom Maser) was put online.  
On DOY 060 (MJD 55621), SPC 60 HM2 (Symmetricom) was put online.


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.
