Notes. Comparisons of EW0-related values in two methods: one based on realistic variable β and the other based on the assumption of β = −2.0. (1) Method; (2) (3) (4) mean, median, and standard deviation of EW0; (5) scale factors for the entire sample; and (6) scale factors for the limited subsample with MUV<−18.5.
