V/69        MK, UBV Time and Latitude Stars       (Sato+ 1990)

MK Classification and Photometry of Stars Used for Time and Latitude Observations at Mizusawa and Washington Sato K., Kuji S. <Astron. Astrophys. Suppl. Ser. 85, 1069 (1990)> =1990A&AS...85.1069S
ADC_Keywords: MK spectral classification ; Photometry, UBV Description: MK spectral classifications are given for 591 stars which are used for time and latitude observations at Mizusawa and Washington. The classifications in the MK system were made by slit spectrograms of dispersion 73 A/mm at H-gamma which were taken with the 91cm reflector at the Okayama Astrophysical Observatory. Photometric observations in UBV were made with the 1-meter reflector at the Flagstaff Station of U.S. Naval Observatory. File Summary:

Note (1): the program names are as follows: V1 = VZT stars for the period 1899 - 1980, V2 = VZT stars for the period 1980 - 1987, F1 = FZT stars for the period 1942 - 1967, F2 = FZT stars for the period 1967 - 1987, A = Astrolabe stars, P = PZT stars Note (2): the quality has the following meaning: G = good, SLU = slightly under exposure, SOV = slightly over exposure, BRO = broken but used for classification, FOG = foggy
