Broadband Photometry of Northern-Hemisphere Luminous Stars. VII. UBV Photometry for 38 Case-Hamburg Stars CCD-based UBV photometry for 38 intrinsically luminous stars drawn fromvolumes II, III, and IV of the Luminous Stars in the Northern Milky Waycatalog is reported. Most were imaged three or four times. These objectsinclude a number of bright giants and supergiants of spectral types B,A, and F. All but two are previously unobserved photometrically.
UBV beta Database for Case-Hamburg Northern and Southern Luminous Stars A database of photoelectric UBV beta photometry for stars listed in theCase-Hamburg northern and southern Milky Way luminous stars surveys hasbeen compiled from the original research literature. Consisting of over16,000 observations of some 7300 stars from over 500 sources, thisdatabase constitutes the most complete compilation of such photometryavailable for intrinsically luminous stars around the Galactic plane.Over 5000 stars listed in the Case-Hamburg surveys still lackfundamental photometric data.
