Fast Determination of Constellation Membership (1008.3966v1)
Published 24 Aug 2010 in astro-ph.IM
Abstract: The 88 constellations as defined by the IAU segment the sky into regions, separated by an intricate set of boundaries. A binary tree decomposition of this landscape is given which tessellates the celestial sphere into rectangles. This allows a fast determination of the constellation membership of any given sky coordinate.
