    Note: the "Actual eccentricity at epoch" is for the benefit of analysts using
    models that produce elements in which the eccentricity corresponds to the
    argument of perigee at epoch, who may wish to compare my results to theirs. I
    use the SGP4 model, which states the eccentricity for zero argument of perigee.
    SGP4 computes the actual eccentricity internally, when propagating elements,
    i.e. when making predictions.
