J/BaltA/10/349   Vilnius photometry in Cam/Per   (Zdanavicius+, 2001)

Photometric classification of stars and the interstellar extinction near the Camelopardalis and Perseus border. Zdanavicius J., Cernis K., Zdanavicius K., Straizys V. <Baltic Astronomy, 10, 349 (2001)> =2001BaltA..10..349Z
ADC_Keywords: Photometry, Vilnius ; Molecular clouds Keywords: interstellar medium: clouds, extinction - stars: fundamental parameters, distances - techniques: photometric 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. File Summary:

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
