Photoelectric UVBY beta photometry of 230 stars brighter than m(pg) = 13.0 in the two B = +75 deg fields SA 80 and SA 81
The study presents uvby and beta photometry for 123 and 107 stars in SA80 and SA 81 brighter than m(pg) = 13 and earlier than G1. Most starsseem to be of type A or F with sample limits V is not greater than 12.6and beta is not less than 2.60. SA 80 and SA 81 have 34 and 27 BD starsin common with a general b is not less than 70 deg program,respectively. uvby photometry for 19 and 12 stars fainter than m(pg) =13 is also presented. If situated on the standard line, the sample ofabsolutely less luminous F9-G0 stars are complete in the volume confinedto the distance range from 80 to 300-400 pc. Several lines of sight haveE(b-y) exceeding 0.050 m. In both areas the remote A stars seem to bevirtually unreddened or are perhaps bluer than typical for population Istars. SA 80 covers part of the Virgo cluster, and the data may be usedto estimate the galactic reddening in this direction.

Kinematics and properties of F stars near the North Galactic Pole. II - The isothermal disc
Radial velocities are given for about 550 photometrically-identifieddisk-population F stars lying within 15 deg of the North Galactic Pole.The overall radial and z-velocity distributions are found to be closelyGaussian, with corrected rms and mean z velocities of 11.3 + or - 0.6and -9.5 + or - 0.5 km/s, respectively. The isothermal kinematics of thepopulation are reflected in the constant velocity dispersion to a zdistance of 400 pc. No systematic variation of either the velocitydispersion or the stellar age with the metallicity-sensitive Stromgrendelta m1 index is noted over a range of ages up to 5 Gyr.
