Photometric Study of the Open Cluster NGC 225.

Abstract (from CDS):

NGC 225 is a young moderately populated cluster with discrepant age, distance, and color excess estimates reported by different authors. We combine our photometry with the data from large surveys (2MASS, WISE, Pan-STARRS) to derive the parameters of NGC 225 and study the extinction law in the near infrared in the direction of the cluster. We use theoretical isochrones to infer the color excess E(B-V)=0.29±0.01, distance D=667±18 pc, and Age = 100-160 Myr. We fit extinction in the infrared by a power-law relation, λ-α, and find α=2.16±0.34.
