Every star # was searched with a 3' radius in SIMBAD to find additional IDs. The notes # include most of the original comments; some entries have my comments added at # the front (all the external IDs given are new). # Using photometric data from the TASS MkIII survey (2000PASP..112..397R, # II/230), I have added two columns showing V and V-I to 0.1-mag. precision # for stars with a close match in position (~5"). These help confirm the # very-red nature of the stars. # Some of the stars are not especially red, # and the spectral types cannot be # as late as indicated. This is likely to be the case when there is no IRAS or # MSX detection. Two stars do not appear on extant digitized sky surveys. # Rather than being extraordinarily red, I suspect these are instead plate flaws # in the Byurakan material. Such extreme red objects would not have escaped # being detected in IRAS or MSX surveys, and are unlikely to be missing on two # or three epochs of the sky surveys (POSS-I and UK Schmidt). # The text indicates that the red magnitudes and b-r colors were determined # using image diameters on POSS-I prints, and are not from one of the plate-scan # survey catalogues. # # # source: 2001Ap.....44...88G # GIGOYAN K.S., ABRAHAMYAN H.V., AZZOPARDI M., and RUSSEIL D. # Astrophysics, 44, 88-97 (2001) # First Byurakan spectral sky survey.
