A photometric study of the two poorly known northern open clusters NGC 133 and NGC 1348.
Abstract (from CDS):
We present CCD UBVI observations obtained in the field of the previously unstudied northern open clusters NGC 133 and NGC 1348. We argue that NGC 133 is a heavily contaminated cluster, for which we identify 13 candidate members down to V=14.50mag on the basis of the position in the two-color Diagram. Membership has been checked against proper motions from Tycho 2, whenever available. The cluster turns out to have a reddening E(B-V)=0.60±0.10mag, to be 630±150pc distant from the Sun, and to have an age less than 10Myrs. NGC 1348 is a more reddened clusters (E(B-V)=0.85±0.15mag) for which we isolate 20 members. The cluster lies at a distance of 1.9±0.5kpc away from the Sun, and has an age greater than 50Myrs.
