Hi the refval are the values given as example in the link I gave (function spherical_polar_angle). I put that just as comparison. 220.89 is East-of-North, whereas 229.1066 is the angle...

Just another thing: the two angles are such that phi1+phi2=180. Since the main effect of the different definition is on how the tangential/cross ellipticity components are computed, maybe the solution...
