Abstract:
The results of CCD photometry in the Vilnius seven-color system down
to V=18mag are presented for 242 stars in the direction of the
young open cluster IC 1805 that is located in the active
star-forming region W4 in the Cas OB6 association. Photometric data
were used to classify stars into spectral and luminosity classes, and
to determine their interstellar reddenings, extinctions and distances.
Description:
Table 1 contains the results of photometry of 242 stars down to
V=18mag in the Vilnius seven-color system in the direction of a young
open cluster IC 1805. Photometric data are used to classify stars in
spectral and luminosity classes. The identification numbers,
coordinates, V magnitudes and six color indices in the Vilnius system,
photometric spectral types and membership estimates are given. VSA are
numbers from Vasilevskis et al. (1965AJ.....70..806V 1965AJ.....70..806V), and MJD are
numbers from Massey et al. (1995, Cat. J/ApJ/454/151). The coordinates
are from the PPMXL catalog (Roeser et al., 2010AJ....139.2440R 2010AJ....139.2440R, Cat.
I/317>.
