Cross-correlation length as a function of M_* − 〈M_λ310〉 or M_* − 〈M_λ220〉. 〈M_λ310〉 and 〈M_λ220〉 are the average absolute magnitudes of galaxies measured at rest-frame wavelengths of 310 nm and 220 nm, respectively, and the cross-correlation lengths were calculated by using the galaxy samples which are brighter than the threshold magnitude. Dotted lines represent functions of equation (20) fitted to the data points. (Color online)
