In addition to the large number of newly determined COMMENT fundamental data, such as photoelectric magnitudes, MK spectral types, COMMENT parallaxes, and radial velocities, the new version contains new data and COMMENT information not included in the third edition. Valuable information, COMMENT such as the identification of IR sources, U-B and R-I colors, radial COMMENT velocity comments (indication and identification of spectroscopic and COMMENT occultation binaries), and projected rotational velocities, is included COMMENT for the first time in the fourth addition, while the equatorial COMMENT coordinates for equinoxes 1900 and 2000 are recorded to greater COMMENT precision (0.1 sec in right ascension, 1 arcsec in declination). The COMMENT remarks section of the catalogue has been expanded and improved to COMMENT contain many details concerning variability, spectral characteristics, COMMENT duplicity, and group membership, and the remarks have been segregated by COMMENT category to improve information retrieval and readability. The COMMENT catalogue in general contains data compiled through 1979; however, some COMMENT information and variable-star designations found through 1981 are COMMENT included in the remarks and many variable-star names have subsequently COMMENT been transferred to the data file.
