The Lenses Structure and Dynamics Survey (LSD) Survey aims at measuring the internal kinematics of early-type lens galaxies covering the largest possible range in masses and redshifts. The LSD Survey is described in our publications.
To provide a complete database, together with our
measurements we post measurements from the literature (please
e-mail one of us to notify of existing measurements not included). In
the following table we list the systems for which measurements are
currently available (in colors when our measurement is available).
Click on the object name for more information. Note that most of the
Hubble Space Telescope images used in conjunction with the
spectroscopic data are from the CASTLES database.
