I see the problem, I'll figure out a better way to structure the
computations.

Yes, I think that is what is happening here, but I don't know how to
repair it.
How does the
instability manifest itself.
When psi is 0, then sin(psi) = 0 and you're dividing by it. Needs a
check, that is what I did. Does it help?
I'll try to look more into it later.

That function enters into numerical instability when
sin_tilt_sin_psi==0, which produces psi ==0. I've tried to fixe it,
and i think is correct, but now the code throws the exception. The
input and output are "apart". Can anybody help me to fix it?
