◆ derive_scat_species_a_and_b()

void derive_scat_species_a_and_b ( Numeric a,
Numeric b,
const Vector x,
const Vector mass,
const Numeric x_fit_start,
const Numeric x_fit_end 
)

Derives a and b for relationship mass = a * x^b

The parameters a and b are derived by a fit including all data inside the size range [x_fit_start,x_fit_end].

The vector x must have been checked to have at least 2 elements.

An error is thrown if less than two data points are found inside [x_fit_start,x_fit_end].

Returns
a Derived a parameter.
b Derived b parameter.
Parameters
xSize grid
massParticle masses
x_fit_startStart point of x-range to use for fitting
x_fit_endEndpoint of x-range to use for fitting
