This is the astronomical catalog of near-Earth stars collected during the Origins I Survey. The cataloging method is an extension of the Hubble and Hoyle Guide Star Catalog (GSC). The sky was divided into 38,148 small square regions – established by dividing the sides of each of the GSC sky regions in half. The regional squares are arranged so that 00001 is centered on α Ursæ Minoris, and Regional Square 38148 is centered at the south pole. An example of an OS-I catalog entry is OSI 09158+125A. The first series of digits is the sky region. The second series with the “+”is the serial number within that region. Multiple star systems further identify the stars within the system with a unique alphabetical letter assigned by relative brightness – brightest to dimmest.
