λ_Re relations with global parameters for the sample of 300 CALIFA galaxies. Galaxies are color-coded with Hubble type. Top left panel: whisker plot enclosing the interquartile range (IQR), defined at IQR25%–IQR75% for galaxies of each morphological type. The whiskers extend out to the maximum or minimum value of the data, or to 1.5 times IQR25% or IQR75% in case there is data beyond this range. Outliers are identified with small circles. Other panels: relations with r-band absolute magnitude M_r, total stellar mass M_⋆, u − r Petrosian color, concentration index R₉₀/R₅₀, and star formation rate SFR. See text for details.
