We can compute the detector_direction_x and detector_direction_y vectors as follows:
It is 2.0960759873050085e-06, which is relatively close to zero.
We can compute the angle between these two vectors as follows:
math.acos(dot_product) * 180.0 / math.pi
The angle is 89.99987990369239. One might argue that it is 90 degrees once we account for numerical inaccuracies.
However, it raises an error as numpy.isclose(dot_product, 0) returns False.
It would be great if the user could overwrite the tolerance parameters.
