| Sumario: | A photoelectric spectrum scanner attached to the 16-inch telescope of the Cerro Tololo Inter-American Observatory was used to determine the relative spectral intensity distribution for early type stars. Observations on a minimun of three nights per star have been obtained for about two hundred stars. The tracings extend from 3100 Å to 6000 Å. They were obtained with a slit width from 50 Å to 80 Å , and thus can be used also for a determination of the equivalent widths of H-beta, H-gamma, and H-delta, As a byproduct precise information on the monochromatic atmospheric extinction at Cerro Tololo is obtained. In this investigation special, emphasis was given to Be stars. |
