General Description

VIMOS-IFU spectroscopy of three early-type gravitational lens galaxies.
 The aim is obtain two-dimensional kinematic fields of each target, which can be
 combined with lensing constraints, as obtained from HST image. A joint analysis
 of these data will be used to contrain the internal mass structure of the  early-type
 lens galaxies, in particular their dark matter distribution and stellar mass-to-light
 ratio. The latter results will be compared with simulations and studied for evolution
 with redshift or trends with galaxy mass.

Special Execution Requirements

The target galaxy should be positioned as close to the center of the IFU
 FOV (27"x27") as possible for
SDSS-0655 and SDSS-0645. For SDSS-0472, the target has two nearby dwarf galaxies
 which should also
be inside the FOV of the IFU. Hence, the main galaxy should be slighly offset to
 the west from the IFU FOV center. See attached finding charts (esp. the SDSS ones)
 for the orientations of the IFU.
