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. | ||
