Problem for parameters of zstack

[Hsiang-Chun Wei]

Please help me to define the parameter of zstack.

The definition in example code:

zstack = np.arange(1.08e-3, 1.18e-3, 0.01e-3) # distances from camera to reconstruct

The definition in ps_propagate method:

d = distance from pinhole to reconstructed image, in meters (this is z in Jericho and Kreuzer). Can be a scalar or a 1D list or array.

Thank you very much.
