pb06, jdtt, bzeta, bz, btheta

[SOFA] Returns three Euler angles bzeta (1st rotation, radians clockwise around z), bz (3rd rotation, radians clockwise around z), btheta (2nd rotation, radians counterclockwise around y) which implement general precesion from epoch J2000.0, using the IAU 2006 model, for TT Julian Date jdtt. Frame bias (the offset between ICRS and J2000.0) is included. The three output variables get the same dimensions as jdtt.
