摘要：

Kinematic observations along the major and minor axis of the E5 dwarf elliptical galaxy NGC 205 are presented. We measure a velocity dispersion of 60 km s-1 over the central 1′ with no significant rotation. The upper limit on rotation about either axis is 25 km s-1, and implies an anisotropic velocity distribution. We deduce script M sign/LB = 7 in solar units.
