Abstract:
157 stars down to 11th mag in a 3°x4° area at l=149°,
b=-0.3° have been measured in the Vilnius photometric system.
Magnitudes V, color indices, spectral classes, absolute magnitudes,
color excesses and distances of the stars are determined. The
interstellar extinction in all the area appears at a distance of about
100pc, grows monotonically and at a distance of 500pc it reaches ∼2mag
in the area of the dark cloud L1391 and 0.7-1.7mag in the remaining
area. At larger distances the extinction is affected by a selection
effect.

Note (1): The standard deviation Qsp is calculated using the differences
of all the dereddened color indices of the program star and the
closest standard star.
Note (2): Quality of VMAG as follows:
a = all the used classification methods give sufficiently close
absolute magnitudes, ΔVMAG<0.4mag
b = intermediate cases, 0.4mag<ΔVMAG<1.4mag
c = stars with ΔVMAG>1.4mag
