Vilnius Photometry of Stars in the Area of SA 57
Interstellar reddening, as a function of distance in the direction ofthe North Galactic Pole (SA 57), is determined using the two-dimensionalclassification of 63 stars observed in the Vilnius photometric system.The average value of A_V calculated for the stars up to 800 pc distanceis close to zero (the mean value is A_V=0.01 mag) with a standarddeviation of the order of sigma =+/- 0.1 mag. This dispersion of pointsis exactly what is expected from the errors of measurement andclassification.
