Query: Detailed Cluster Mass and Light profiles of A1703, A370 and RXJ1347-11
  from Deep Subaru Imaging   Weak lensing work can be badly compromised by unlensed foreground and cluster
members which dilute the true lensing signal. We show how the lensing amplitude
in multi-colour space can be harnessed to securely separate cluster members
from the foreground and background populations for three massive clusters,
A1703 (z=0.258), A370 (z=0.375) and RXJ1347-11 (z=0.451) imaged with Subaru.
The luminosity functions of these clusters when corrected for dilution, show
similar faint-end slopes, \alpha ~= -1.0, with no marked faint-end upturn to
our limit of M_R ~= -15.0, and only a mild radial gradient. In each case, the
radial profile of the M/L ratio peaks at intermediate radius, ~=0.2r_{vir}, at
a level of 300-500(M/L_R)_\odot, and then falls steadily towards
~100(M/L_R)_{\odot} at the virial radius, similar to the mean field level. This
behaviour is likely due to the relative paucity of central late-type galaxies,
whereas for the E/S0-sequence only a mild radial decline in M/L is found for
each cluster. We discuss this behaviour in the context of detailed simulations
where predictions for tidal stripping may now be tested accurately with
observations.
