Abstract:
    We present a statistical analysis of a sample of 20 strong lensing
    clusters drawn from the Local Cluster Substructure Survey, based on
    high-resolution Hubble Space Telescope imaging of the cluster cores
    and follow-up spectroscopic observations using the Keck-I telescope.

Description:
    High-resolution imaging data taken with the Advanced Camera for
    Surveys (ACS) or Wide Field Planetary Camera 2 (WFPC2) instrument on
    HST are available for each selected cluster in one or two bands,
    either through our dedicated LoCuSS programme (GO-DD 11312, PI: G.P.
    Smith) or from the archive.

    J- and KS-band data were obtained between 2003 March and 2007 April on
    the following near-infrared instruments: Wide Infrared Camera (WIRC)
    on the Palomar-200-inch telescope, Infrared Side Port Imager (ISPI) on
    the CTIO Blanco 4-m telescope and Florida Infrared Imaging
    Multi-Object Spectrograph (FLAMINGOS) on the Kitt Peak (KPNO) 4-m
    telescope.

    We used the LRIS on the Keck-I telescope to perform long-slit and
    multislit observations of the clusters. The spectroscopic data used in
    the current paper are the outcome of six different observing runs
    between 2004 and 2008.
