Scientific paper

New uvby and/or H-beta photometry is obtained at the Chiran high-altitude outstation for 105 stars. Certain of the program stars are selected from a comparison of the SCAP 2000 balloon-ultraviolet sky survey of the Laboratoire d'Astronomie Spatiale with the corresponding blue and red prints of the Palomar Observatory sky survey. Only a small portion of these stars turn out to be B stars, whereas, the rest of the stars, which are selected from a variety of other sources, are mostly B stars and if of normal luminosity are in many cases many Population I scale heights from the galactic plane. It is shown that the identification of B stars is practicable only at a good observing site and that if H-beta photometry is also obtained, sdOB, sdB, and hot horizontal branch B stars can be distinguished from normal stars by their position in the beta/c(0) diagram.
