The intermediate-age open clusters Ruprecht 61, Czernik 32, NGC 2225 and 2262
We present the first BVI CCD photometry to V= 22.0 of four fieldscentred on the region of the southern Galactic star clusters Ruprecht61, Czernik 32, NGC 2225 and 2262 and of four displaced control fields.These clusters have never been studied before, and we provide for thefirst time estimates of their fundamental parameters, specificallyradial extent, age, distance and reddening. We find that the fourclusters are all of intermediate age (around 1Gyr), close to the Sun andpossess lower than solar metal abundance.
