Function Documentation

◆ get_step()

void get_step	(	const PolarizationHolder &	ph,
		vec3 &	loc,
		vec3 &	dir,
		double	theta
	)

Steps from loc in direction dir for an angle theta and updates loc and dir.

◆ runge_kutta_step()

void runge_kutta_step	(	vec3 &	loc,
		vec3 &	dir,
		const PolarizationHolder &	ph,
		double	theta
	)

Performs one Runge-Kutta second order step. Updates loc and dir.

Definition at line 113 of file alice3.cc.

◆ runge_kutta_2()

void runge_kutta_2	(	const vec3 &	location,
		const PolarizationHolder &	ph,
		double	theta,
		arr< vec3 > &	locs
	)

Second order Runge-Kutta integration on the sphere. Given a starting location, a qu map of the sky, and a step size theta, this subroutine returns an array of vectors extending in both directions from the starting location.

Definition at line 128 of file alice3.cc.

◆ make_kernel()

void make_kernel ( arr< double > & kernel )

Create a sinusoidal kernel.

Definition at line 153 of file alice3.cc.

◆ convolve()

void convolve	(	const arr< double > &	kernel,
		const arr< double > &	raw,
		arr< double > &	convolution
	)

Convolve an array with a kernel.
