Pulkovo compilation of radial velocities for 35495 stars in a common system. Not Available
Radial velocity measurements. II - Ground-based observations of the program stars for the HIPPARCOS satellite New radial velocities for 446 stars of magnitude 9.0 or brighter in 1616-sq-deg fields of the Northern Hemisphere are determined by automaticPDS measurement of 80-A/mm-dispersion spectra obtained at theObservatoire de Haute Provence using a 17-cm-diameter objective prism.The fields were selected to provide data for the input catalog of theESA Hipparcos astrometric satellite. The measurement techniques andprecision are discussed, and the results are presented in extensivetables and graphs.
VRI photometry of selected SAO stars Johnson V, R, and I photoelectric photometry has been obtained for 199SAO stars in support of the Near Infrared Photographic Sky Survey. Thesedata are utilized in the calibration of survey photographs and arepresented here to assist other programs reliant upon access tophotometry in the photographic infrared.
