Abstract
Magnitudes and colours on the UBV system are given for 550 stars of spectral types F, G and K (classes I–V) derived from a second series of photoelectric observations made at the Kitt Peak National Observatory. The ( B–V ) scale shows no significant differences in zero point compared with the Cape Equatorial Zone photometry and the Arizona–Tonantzintla catalogue. The same is true of ( U–B ) except for ( U–B ) > 1 m .8 where difficulties in calibration were encountered. There are significant differences in Δ V , up to 0 m .02 and correlated with right ascension.Keywords
