zero division error in Image Simulation tutorial

[asebian]

As I am working trought the Image Simulation notebook the OPD graph does not show anything. There seems to be an issue with the change from the Zernike to the Forbes polynomial base.

basis = list(polynomials.qpoly.Q2d_sequence(nms, r_aber, t))
print(basis)

C:\ProgramData\intelpython3\lib\site-packages\prysm\polynomials\qpoly.py:846: RuntimeWarning: divide by zero encountered in scalar divide
  Q0 = 1 / (2 * f0)
