FTS Report on DOY 173

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. 
On DOY 152 (MJD 55713), SPC 10 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.
