β vs. M₁₅₀₀. Black triangles represent the CEERS sources with β slope obtained fitting 3 or 2 photometric bands. Red dots are for the GLASS sample, and blue squares are for the ERO sample. The green line shows the relation at z ∼ 7 derived from HST data by Bouwens et al. (2014). Dashed portions indicate the extrapolation of the relation in our range of M₁₅₀₀. The Spearman rank correlation coefficient for the correlation between β and M₁₅₀₀ is 0.36, with a p-value of 0.02.
