    time correction, applied to the spacecraft-to-Mars center
      vector, is at the 1 cm level.

      Comparison of results obtained using the one-iteration and
      converged light time solutions is recommended when adequacy of
      the one-iteration solution is in doubt.


      Converged corrections
      ---------------------

      When the requested aberration correction is &quot;CN&quot;, &quot;CN+S&quot;,
      &quot;XCN&quot;, or &quot;XCN+S&quot;, as many iterations as are required for
