Function Documentation

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

x	Size grid
mass	Particle masses
x_fit_start	Start point of x-range to use for fitting
x_fit_end	Endpoint of x-range to use for fitting
