Abstract:
The area of the open cluster NGC 2395 in Gemini is investigated by CCD
photometry in the Vilnius seven-color system. Magnitudes, color
indices, photometric spectral types, color excesses, interstellar
extinctions and distances are determined for the 163 stars down to
V=15.75mag in the 25' diameter area.
Description:
Observations took place on two nights - 2003 March 2/3 (U, Z, V and S
filters) and March 6/7 (P, X and Y filters).
