The results of RGU photometric measurements of 2647 stars (down to limiting G magnitude 17.7) of a 0.167-sq deg field (S1-prime) toward Sct are combined with those for the larger concentric fields S1 (Becker, 1962) and Sa + 1/2(Sb) (Karaali, 1979), presented in tables and (U-G)/(G-R) two-color diagrams, and used to derive a reddening function and the logarithmic space-density functions for late-type giants and main-sequence stars in consecutive absolute-magnitude intervals. Three absorption screens causing mean accumulated reddenings E(G-R) = 0.38, 0.74, and 1.36 mag are located at 300 pc, 1.00 kpc, and 2.31 kpc, respectively. The luminosity function based on complete categories in the distance interval 200-800 pc is shown to have the same slope as that for the solar neighborhood (Gliese, 1969) but at slightly higher values.
