A catalog of K giants at the South Galactic Pole - Broadband and DDO photometry and radial velocities
We describe a sample of K giants at the South Galactic Pole, selected toexamine the chemical and kinematical properties of stars perpendicularto the galactic plane and to measure the local column density of thedisk. We report velocities, abundances, absolute magnitudes, andbroadband BV photometry for over 500 giants.

CA II H and K measurements made at Mount Wilson Observatory, 1966-1983
Summaries are presented of the photoelectric measurements of stellar CaII H and K line intensity made at Mount Wilson Observatory during theyears 1966-1983. These results are derived from 65,263 individualobservations of 1296 stars. For each star, for each observing season,the maximum, minimum, mean, and variation of the instrumental H and Kindex 'S' are given, as well as a measurement of the accuracy ofobservation. A total of 3110 seasonal summaries are reported. Factorswhich affect the ability to detect stellar activity variations andaccurately measure their amplitudes, such as the accuracy of the H and Kmeasurements and scattered light contamination, are discussed. Relationsare given which facilitate intercomparison of 'S' values with residualintensities derived from ordinary spectrophotometry, and for convertingmeasurements to absolute fluxes.

Uvby-beta photometry of visual double stars - Absolute magnitudes of intrinsically bright stars
Individual absolute visual magnitudes M(v) are derived for intrinsicallybright stars and evolved stars. The results are collected for 106objects believed to be members of binary systems. uvby-beta photometrywas empirically calibrated in terms of M(v) for main sequence stars andphotoelectrically determined apparent magnitudes. The derived M(v)values are not significantly different from those stated in the Wilsoncatalogue (1976). Binary systems with main sequence primaries andsecondary components off the main sequence were also investigated.Several systems in which at least one component may be in the pre-mainsequence contraction stage are pointed out. A wide variety of commentsand derived data are given individually for 136 double stars, includingmetallicities, distance moduli, and masses.
