Query: A Pilot Study of the Tully-Fisher Relation in Cl0024+1654 at z=0.4   We present the first determination of the Tully-Fisher relation (TFR) for a
distant galaxy cluster. We have measured internal kinematics of seven members
of Cl0024+1654 from spatially resolved emission observed in 2D Keck (LRIS)
spectra. Measurements of disk structural parameters were made from HST (WFPC2)
images. While we do not find evidence for a change in the slope or zeropoint of
the cluster TFR, we do find that there was more scatter in the past. We intend
to expand this study with kinematic measurements from fifteen more Cl0024
members.
