ADC_Keywords: Photometry, UBV ; Photometry, uvby, beta ; Radial velocities ; MK spectral classification ; Stars, luminous ; Milky Way Description: This catalog contains databases of published photoelectric UBVbeta data, MK-system spectral classifications, and Stroemgren four-color uvby photometry for objects in the Stephenson-Sanduleak "Luminous Stars in the Southern Milky Way" catalog (LSS catalog). The catalog contains mostly OB stars and A and F supergiants. These databases have been compiled from the literature. File Summary:
