Abstract:
Beijing-Arizona-Taiwan-Connecticut (BATC) multiband photometric data
in the field of open cluster M48 are used to determine its membership.
By comparing observed spectral energy distributions of M48 stars with
theoretical ones, membership probabilities of 750 stars with limiting
magnitudes of 15.0 in the BATC c band (λeff=4194Å) are
determined. We find 323 stars with membership probabilities higher
than 30% that are considered to be candidate members of M48. Comparing
membership probabilities of 229 stars obtained in common between the
present method and proper-motion-based methods, an 80% agreement among
these methods is obtained
