Observations of O and B stars
Listed in IVOA Registry (Virtual Observatory)
This catalog of O and B stars contains magnitudes, colors, spectral types and polarization for 1259 stars.
Description
In addition to observations, the catalogue contains the derived absorption and distance modulus. A photoelectric photometer attached to the 82-inch (2m) reflector of the McDonald Observatory was used for the polarization observations.
The photometric UBV observations were made over a period of 4 years with the 13-inch (33cm) and the 82-inch telescopes at McDonald. The spectroscopic classification was made with a new camera installed on the Cassegrain spectrograph, with a dispersion of 86{AA}/mm at H{delta}.
