// <p>Computes data related to Eckstein Hechler orbit propagation analytical model.</p>
// <p>These data are: </p>
// <p> - Eccentricity vector of frozen orbit </p>
// <p> - Secular drifts of some angular orbital elements </p>
// <p></p>
// <p>The output is a structure with the following fields:</p>
// <p> - infos.exf: Mean eccentricity vector x-component of frozen orbit</p>
// <p> - infos.eyf: Mean eccentricity vector y-component of frozen orbit</p>
// <p> - infos.dgomdt: Secular drift of mean right ascension of ascending node [rad/s]</p>
// <p> - infos.dpsodt: Secular drift of mean argument of latitude [rad/s]</p>
// <p></p></listitem>
// <listitem> 
// <p><b>Note:</b></p>  
// <p>The outputs only depend on semi major-axis and inclination. </p>
