I support the statement yaw=azimuth and
pitch=elevation. IMHO, the correct order for the
rotation is yaw, pitch, roll. I think this is always
the case, however the calling function you are
using may be using the order [pitch,yaw,roll],
but this is just the order of the argument, not the
order of the execution of the rotations.
Hope this help
