The code used an interpolation scheme from a pre-calculated table to obtain the expected QSO number counts as a function of redshift and magnitude.
The original code used scipy.interpolate.interp2d with a cubic spline, but this routine is being deprecated. I have updated the code to instead use scipy.interpolate.RectBivariateSpline also with a cubic spline. Testing shows that the results are the same for a range of redshift and magnitudes between the two methods.
