Notes
Wraps ERFA function
eraC2s. The ERFA documentation is:- - - - - - - e r a C 2 s - - - - - - - P-vector to spherical coordinates. Given: p double[3] p-vector Returned: theta double longitude angle (radians) phi double latitude angle (radians) Notes: 1) The vector p can have any magnitude; only its direction is used. 2) If p is null, zero theta and phi are returned. 3) At either pole, zero theta is returned.
