Kinematic Properties and Stellar Populations of Faint Early-Type Galaxies. II. Line-Strength Measurements of Central Coma Galaxies

We present line-strength measurements for 74 early-type galaxies in the core of the Coma cluster reaching down to velocity dispersions, sigma , of 30 km s-1. The index- sigma relations for our sample, including galaxies with sigma < 100 km s-1 (low- sigma ), differ in shape depending on which ind...
