III/222  14th General Catalogue of MK Spectral Classification    (Buscombe 1999)

MK spectral classifications, 14th General Catalogue, Epoch 2000, including UBV photometry Buscombe W. <Northwestern Univ., Evanston, Illinois ISBN 0-939160-12-9 (1999)>
ADC_Keywords: Spectral types ; Photometry, UBV Description: This is the fourteenth in a series of catalogs of MK spectral types and UBV photometry issued from Dearborn Observatory. It is based on an extensive search of the literature published from ∼1997 to 1999. 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. File Summary:

1- 11 A11 --- Id ? Identification for star (1) 14- 15 I2 h RAh Right Ascension (B2000) hour 17- 20 F4.1 min RAm Right Ascension (B2000) minute 21 A1 --- u_RAm [:] uncertain, tenths digit not listed 23 A1 --- DE- Declination sign 24- 25 I2 deg DEd Declination (B2000) degree 27- 28 I2 arcmin DEm ? Declination (B2000) minute 30- 51 A22 --- SpType MK type (2) 52 A1 --- n_SpType [*] '*' for a standard 53- 57 F5.2 mag Vmag ? Johnson V magnitude 58 A1 --- u_Vmag [m] mean flag (3) 59- 63 F5.2 mag B-V ? Johnson B-V color 65- 69 F5.2 mag U-B ? Johnson U-B color 75- 80 A6 --- Name Alternate identification, usually HD (1)
Note (1): The alphabetical letters starting at byte 1 (column 1 of Id) refer to the components of multiple systems included in SpType, while those at byte 76 (column 2 of Name) indicate which were included in the photometry. Note (2): A colon denotes uncertainty, parentheses denote an inferred assignment. The prefix 'D' is for white dwarfs. 'SD' is for subdwarfs. 'WL' indicates metal poverty compared to solar composition: 'WLS': -0.3 > [Fe/H] > -0.9 'WLM': -0.9 > [Fe/H] > -1.5 'WLE': -1.5 > [Fe/H] Note (3): The letter 'm' for mean indicates mean magnitude of a variable star. (The print version indicates mean magnitudes within angle brackets like <14.8>).
History: * ADC received electronic data files for this catalog from William Buscombe in July 1999, and one file was resent in January 2001. Some corrections were applied by Dr. Buscombe in March 2001, based on recommendations from S. Nishimura of Japan's Astronomical Data Analysis Center. These corrections have been made to the ADC version of the catalog. Acknowledgements: Courtesy of William Buscombe, Dearborn Observatory with computing assistance from Bruce E. Foster.
