FTS Report on DOY 040

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:
* Values derived from linear least squares extrapolation or interpolation

$ On DOY 38 (MJD 53408), MASER 1 went offline for VCO upgrade.
  MASER 2 online for duration of upgrade.

& On DOY 39 (MJD 53409), MASER 1 back online with a higher
  performance VCO improving the phase noise ~6dB
