摘要：

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 (lambda(eff) = 4194 angstrom) 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.
