Morphological parameters of galaxies from Spitzer

The morphology of galaxies can be quantified to some degree using a set of scale-invariant parameters. Concentration (C), asymmetry (A), smoothness (S), the Gini index (G), the...借助一组尺度不变参数，可对星系形态进行一定程度的量化表征。具体包括集中度（Concentration, C）、非对称性（Asymmetry, A）、平滑度（Smoothness, S）以及基尼指数（Gini index, G）等……
