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.
