Abstract:
Interstellar extinction in a ∼100 sq. degree area at the
Camelopardalis and Perseus border is investigated. The study is based
on the results of photoelectric photometry of 455 stars in the
seven-color Vilnius photometric system published earlier. The nearest
100 stars with Hipparcos parallaxes show that the extinction starts to
grow at a distance of 110-150pc. At a distance of 1 kpc the
extinction Av is within 1.2 and 2.4mag. At larger distances the
extinction determination is affected by the limiting magnitude effect.
At distances >1.5kpc a number of O-B stars with the extinctions
between 2 and 4mag are found.

Global notes:
Note (G1): Quality flag, defined from the fitting of the Qs:
1 = best fitting, residuals with σ<0.02
2 = 0.02<σ<0.03mag
3 = 0.03<σ<0.04mag
4 = 0.04<σ<0.05mag
5 = σ≥0.05mag
6 = bad
