UC_2013b		(Relative astrometry is derived from individual measurements, not precessed means.
UC_2013b		UCAC aperture magnitudes are listed, unless the duplicity flag indicates a blended
UC_2013b		image (a flag value of 30 or higher). Model fit magnitudes are given for both
UC_2013b		components if either has such a flag. Model fit magnitudes are indicated by the
UC_2013b		letter "f" following the filter information.
UC_2013b		APASS photometry extracted from UCAC4 catalog is listed under reference AAV2012.
UC_2013b		Due to aperture method used, APASS photometry is only included for pairs wider
UC_2013b		than 10" (Henden, private comm.) Photometry for pairs wider than 10" which showed
UC_2013b		identical values for both components in all filters were removed, as well.
