摘要
我们 presenting some preliminary results related to a project aimed at studying the evolution of the galaxy population in rich environments by means of the Color-Magnitude relation and of the Fundamental Plane. 我们推导出 AC118 团簇于 z=0.31 处星系的红外与光学结构参数。我们证明了在 z~0.3 时，仍可从地面观测中推导出可靠的星系结构参数。该红外有效半径，首次在该红移下测得，显著小于从光学数据推导出的半径，这为了解星系颜色梯度演化提供了新视角。
