A photometric catalogue of stars in the direction of the bright cloudB in Sagittarius.
Abstract
The present catalog includes photometric data on stars in a 5.5 deg x 5.5 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 and B-V and U-B colors are reported for nearly all HD and HDE stars in the field and also for a number of interesting stars (402 stars), 21 proper motion stars, and 45 stars in a 15 arcmin radius circular region centered on the galactic cluster Trumpler 26 (Tr 26). Furthermore, photographic B, V, R, and IR magnitudes are listed for 274 stars in the field of Tr 26. These data will be used for further studies of interstellar absorption in the Galaxy's central direction in relation to specific objects (red variable stars, star clusters, diffuse objects).
