| Abstract |
We 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 σ_z/σ_R. Random errors in this
decomposition are 15% at two disk scale-lengths. |
