... In this Letter, we measure the near-infrared indices Na i and DCO for a sample of 12 early-type galaxies in low-density environments and compare them with the Fornax galaxy sample presented by Silva et al.. The analysis of these indices in combination with Lick/IDS indices in the optical range reveals that (1) the Na i index is a metallicity indicator as good as C4668 in the optical range, and (2) DCO is a tracer of intermediate-age stellar populations. ... To answer this Figure 3. ...
