i_par

miepython.rayleigh.i_par(m, x, mu, norm='albedo')

Return the parallel scattered intensity for small spheres.

The default normalization sets the integral of the unpolarized intensity over 4pi steradians to equal the single scattering albedo.

Parameters:

• m – the complex index of refraction of the sphere

• x – the size parameter

• mu – the cos(theta) of each direction desired

• norm – (optional) string describing scattering function normalization

Returns:

The intensity at each angle in the array mu. Units [1/sr]
