Scientific paper

The second Henry Draper Extension, giving spectral classification for about 87000 stars, up to now was published in the form of finding charts only. This catalog contains a first portion (about 10000 stars) of it in the form of a star catalogue, giving spectral types, photographic magnitudes, precise positions (J2000) and, in many cases, also proper motions of the stars HDE 332335 to HDE 342973. Positions are derived from identifications of the HDE stars in the Astrographic Catalogue. The mean error is about 0.3 arcsec. Magnitudes of the stars are taken from the Astrographic Catalogue, for which we estimate an accuracy of about 0.3 mag. To find proper motions the stars were also identified with the PPM catalogue, whenever possible. Proper motions in PPM typically have rms errors smaller than 0.5 arcsec/century. Proper motions are given for about 2500 stars. A detailed description of this catalog was done by Roser et al. (1991). (2 data files).
