Before, when a set of ecliptic coordinates was converted to equatorial ones, the given epoch was broken. Now, it is possible to convert properly ecliptic coordinates for an epoch, to equatorial coordinates for another epoch. It is possible that this work will be improved with a more accurate algorithm from jean Meeus, in the future.
