Caption: Figure 6.

Same as the main plots in Figure 2, but with the metallicity gradients derived using different maximum fitting radii. The maximum fitting radius (in units of Re), the age–metallicity gradient correlation coefficient, and the best-fit slope are listed in the bottom-left corner of each panel.
