Abstract
The Henry Draper Extension Charts (HDEC), published in the form of fin ding charts, contain spectral classifications for roughly 87 000 10 - 11(m) stars. These highly valuable data are virtually unused by modern (computer-based) astronomy. A pilot project performed in 1991 demonst rated the possibility of transforming the HDEC into a star catalog. In this paper, we present a final HDEC catalog, which provides accurate positions, proper motions, magnitudes, and spectral types for 86933 HD EC stars.
