UBVRI CCD Photometry for Open Cluster NGC2506
Abstract
We present CCD measurements taken in UBVRI broadband filters on 2008 19 January using the WIYN 0.9m telescope at Kitt Peak National Observatory under photometric conditions for metal-poor open star cluster NGC 2506. Comparison of color-color diagrams for the cluster fiducial sequence to the Hyades yields a metallicity, [Fe/H] = -0.45+/-0.10, and reddening, E=0.10+/-0.01. Comparison of color-magnitude plots to the Yale-Yonsei 2002 isochrones yields: (m-M)v=12.76+/-0.05 and age=2.10+/-0.05Gyr.
