Pulkovo compilation of radial velocities for 35495 stars in a common system. Not Available
The Case Low-Dispersion Northern Sky Survey. XIV - A-F stars in a region in southern Canes Venatici Positions, estimated magnitudes, and finding charts are provided for 387A-F stars in an about 190 sq deg region in southern Canes Venatici. Thearea encompassed is between R.A. 12h00m and 14h10m and decl. +29 deg 00arcmin and +38 deg 30 arcmin (1950), excluding the region R.A. 12h00m to13h00m and decl. +29 deg to +34 deg, which was covered in a previouspaper. The A-F stars, whose blue magnitudes are within the range 8through 18 (median 14), were identified on low-dispersionobjective-prism plates taken with Case Western Reserve University'sBurrell Schmidt telescope at Kitt Peak.
