wiscombe_terms

miepython.core.wiscombe_terms(x)

Return the number of Mie series terms from Wiscombe’s criterion.

The series is truncated after this many orders so that the summed scattering quantities are accurate to about 1e-6. The low-level an_bn and cn_dn kernels repeat this expression because numba cannot call back into Python.

Parameters:

x – the size parameter of the sphere

Returns:

number of terms, so orders 1 through the returned value
