Member Function Documentation

void SkyMesh::aperture	(	SkyPoint *	center,
		double	radius,
		MeshBufNum_t	bufNum = DRAW_BUF
	)

finds the set of trixels that cover the circular aperture specified after first performing a reverse precession correction on the center so we don't have to re-index objects simply due to precession.

The drawID also gets incremented which is useful for drawing extended objects. Typically a safety factor of about one degree is added to the radius to account for proper motion, refraction and other imperfections.

Parameters

center	Center of the aperture
radius	Radius of the aperture in degrees
bufNum	Buffer to use
