\caption{Differences in the abundances of the distinct chemical species used
to build the 4 models described in the text. The last column shows the
dispersion around the 1:1 relation when comparing the offsets in the indices
between galaxies in different environments and the offsets in the indices due
to the changes in the chemical species of each model. \label{modelillos}}
