Notes. Partial correlation coefficients of age or metallicity gradients and stellar and total mass. Quoted uncertainties correspond to the 95% confidence intervals, and significance levels are indicated according to the associated p-values: ^* * *p < 0.001, ^**p < 0.01, ^*p < 0.05, ^nsnot significant.
