Table 2

Similar to Table 1, but for best-fit correlations between 16 absorption line indices and griz colours.

Notes. The results for HδA, HγA, HδF, HγF are listed in Table 1. The somewhat smaller fitting uncertainties of G4300, Fe4668, Hβ, and NaD result from fewer galaxies (about 2270) used for fitting compared to the results of Table 1.
