double LinearFitPhotometricToHapke	(	double	pPar,
		void *	pParams
	)

Fits a simple photometric model to the Hapke model by linear least squares fit at a contant given value of the limb-darkening parameter pPar.

The RMS error of the fit is returned.

The prototype is set to match the gsl_function data type to use gsl's brentminimizer function.

The gsl_function is a pointer to function of the following prototype: double (* function) (double x, void * params)

Following is an example to use gsl_function struct my_f_params { double a; double b; double c; };

double my_f (double x, void * p) { struct my_f_params * params = (struct my_f_params *)p; double a = (params->a); double b = (params->b); double c = (params->c);

return (a * x + b) * x + c; }

gsl_function F; struct my_f_params params = { 3.0, 2.0, 1.0 };

F.function = F.params =
