dc.descriptionWe analyze integral-field ionized gas and stellar line-of-sight kinematics in the context of determining the stellar velocity ellipsoid for spiral galaxies observed by the Disk-Mass Survey. Our new methodology enables us to measure, for the first time, a radial gradient in the ellipsoid ratio sigma_z / sigma_R. Random errors in this decomposition are 15% at two disk scale-lengths.
