Beginning of ReadMe : III/228 4th General Catalogue of MK Spectral Classification (Buscombe 1980) ================================================================================ MK spectral classifications, Fourth General Catalogue Buscombe W. <Northwestern Univ., Evanston, Illinois ISBN: 0939160021 (1980)> =1980mscf.book.....B =2001yCat.3228....0B ================================================================================ ADC_Keywords: Spectral types ; Photometry, UBV Description: This is the fourth in a series of catalogs of MK spectral types and UBV photometry issued from Dearborn Observatory. It is based on an extensive literature search. Each catalog is essentially self-contained, with its separate selection of stars listed in order of increasing right ascension. Some classifications (indicated between parentheses) are inferred from photometric or astrometric considerations. The preferred identification is from the Henry Draper Catalog or the General Catalog of Variable Stars, with a Durchmusterung or other alternative as space permits.
