KEP Mag |
A magnitude computed according to a hierarchical scheme and depends on what pre-existing catalog source is available, SCP, Tycho 2, or photographic photometry, in order of preferred selection. For SCP stars the magnitude is synthesized from the Sloan-like g and r magnitudes according to the following prescription: if one defines 'color' as g - r, then for color less than or equal to 0.8 kepmag = 0.8r + 0.2g, while for color greater than 0.8 kepmag = 0.9r + 0.1g. Empirical measurements for presumed constant stars suggest that the r.m.s. for this quantity is slightly larger 0.02 mags. except for very faint and bright stars. |

SCP, 2MASS, UNCAL, PHOTO, and TYBV. SCP - SCP values for sdssg and sdssr were used to compute KEPMAG using equation below . The error for KEPMAG is roughly 0.03 mag., NOCAL - No calibration to optical mag. possible, used for entries from non-optical catalogs. KEPMAG field is null. , 2MASS - Objects found only in 2MASS Catalog with no optical counterpart, KEPMAG is null, UNCAL - KEPMAG copied from a single color of the parent catalog, uncertainty could be 1.0 mag or higher, PHOTO - parent catalog contained a red and blue mag. obtained from Photographic photometry. Values used to compute KEPMAG on the basis of: sdssg=blue sdssr=red color=sdssg-sdssr if (color<=0.8) kepmag = 0.8*sdssr + 0.2*sdssg else kepmag = 0.9*sdssr+0.1*sdssg, internal photographic errors have errors of 0.2 mag suggest KEPMAG errors of 0.03 mag, TYBV - parent catalog is Tycho-2 and this gives B and V magnitudes. KEPMAG value computed from sdssg=0.54*b+0.46*v-0.07 sdssr=-0.44*b+1.44*v+0.12 using same transformation as above to calc. KEPMAG. Errors same as for TYCHO-2 catalog. |
