Missing some Earth equatorial radius and flattening for IERS in Constants class
The IERS2003, IERS96 and IERS2010 Earth equatorial radius and flattening are not present in the Constants class whereas for instance WGS84, GRS80 or EGM96 are.
These conventions can be found here (in the technical notes): https://www.iers.org/IERS/EN/DataProducts/Conventions/conventions.html and http://iers-conventions.obspm.fr/conventions_archive.php
