A photometric catalogue of stars in the direction of the bright cloud B in Sagittarius
The present catalog includes photometric data on stars in a 5.5 deg x5.5 deg area in the direction of the bright cloud B in Sagittarius,centered at l equals 357.7 deg, b equals plus 5.6 deg. V magnitudes andB-V and U-B colors are reported for nearly all HD and HDE stars in thefield and also for a number of interesting stars (402 stars), 21 propermotion stars, and 45 stars in a 15 arcmin radius circular regioncentered on the galactic cluster Trumpler 26 (Tr 26). Furthermore,photographic B, V, R, and IR magnitudes are listed for 274 stars in thefield of Tr 26. These data will be used for further studies ofinterstellar absorption in the Galaxy's central direction in relation tospecific objects (red variable stars, star clusters, diffuse objects).
