J/A+A/554/A3        Vilnius photometry of IC1805 stars       (Straizys+, 2013)

The open cluster IC 1805 and its vicinity: investigation of stars in the Vilnius, IPHAS, 2MASS and WISE systems. Straizys V., Boyle R.P., Janusz R., Laugalys V., Kazlauskas A. <Astron. Astrophys. 554, A3 (2013)> =2013A&A...554A...3S
ADC_Keywords: Clusters, open ; Photometry, Vilnius Keywords: open clusters and associations: individual: IC 1805 - open clusters and associations: individual: Cas OB6 - stars: fundamental parameters - ISM: dust, extinction 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), 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, Cat. I/317>. File Summary:
