CCD BVI photometry and Coravel observations of stars in the open cluster NGC 2489
We present CCD BVI photometry for the southern open cluster NGC 2489 and its surrounding field. The sample consists of 2182 stars measured in an area of 13.6 × 13.6 arcmin2, extending down to. These data are supplemented with CORAVEL radial-velocity observations for seven red giant candidates. A clu...
