We complement our study of=Fe enhanced stellar population models of Lick absorption indices (Thomas et al. 2003) by comparing two sets of=Fe enhanced models. In both models the impact on Lick indices due to=Fe enhancement is accounted for through a modification of the stellar absorption line-strengths using the response functions of Tripicco & Bell (1995). One set of models, however, uses solar-scaled, the other =Fe enhanced stellar evolutionary tracks. Since the =Fe enhanced tracks are hotter…
