FTS Report on DOY 214

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.

II.  Frequency Offsets from linear least-squares fits on time-offsets
over the period (54669 to 54678):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
^ Number obtained from the SPC40 GPS true time, with an offset.
& Direct subtraction between columns (SPC40-NIST) and (SPC10-NIST).
% There were not enough common-view SVs between SPC 60 and SPC 10. Direct subtraction was used.
$ Linear extrapolation used. The complex-wide power failure on DOY 214 (MJD 54679) caused the TA computer mother board to fail. 
  The spare TA computer also has a dead mother board. 
  Station personel also reset the MCA, introducing a decrease in frequency of about 227 nanoseconds. 
  Multiple equipment failures made for a difficult recovery. TA still down as of 08/06/08.
