   Data for DSS-35 are based on an email from Dr. William Folkner,
   dated June 13, 2014. The position data from that email are shown
   below:
 
     >> Cartesian coordinates x, y, z (m)
     >>
     >> -4461273.0838  2682568.9220 -3674152.0885
 
   The email states that the position is accurate to about 1 cm.
   It also states that the site velocity for other stations in
   the Canberra complex applies to DSS-35. This velocity is now
   included in the SPK file for this station. The epoch of the data
   is 2003.0. The velocity has been transformed to the ITRF93
   reference frame from the DSS-35_TOPO frame, and it has been
   scaled to units of m/year. The original velocity data are
   included at the end of this file.
 
   Topocentric frame orientations were derived using earth radii
   included below.
 
 
   Data for DSS-36 are based on an email from Dr. William Folkner,
   dated May 28, 2014. The position data from that email are shown
   below:

   Reference Spheroid
   ------------------
 
   The reference bi-axial spheroid is defined by an equatorial and a
   polar radius.  Calling these Re and Rp respectively, the flattening
   factor f is defined as
 
      f = ( Re - Rp ) / Re
 
   For the reference spheroid used by this file, the equatorial radius
   Re and inverse flattening factor 1/f are
 
      Re         = 6378136.3 m
      1/f        = 298.257
 
      Derived Rp = 6356.7516005629377
