· Astrophys. J., v. 199, no. 3, pp. 586-590
A rotation curve is derived for the S0 galaxy NGC 3115 from its absorption-line spectrum. The central velocity is 728plus-or-minus9 km s$sup -1$. The rotation curve rises to 260 km s$sup -1$ at 25'' from the nucleus, and remains constant at that value to the limit of the measurements. A rough computation of the mass gives 2.4times10$sup 10$ M/sub sun/ out to 3.4 kpc, and a mass-to-light ratio of 20 to the same radius.
