Study of the Depletion Effect in the Cluster MS1008-1224
Abstract
We present a detailed study of the depletion effect (the radial manifestation of the magnification bias) in the cluster MS1008-1224. Following our results concerning the simulations of depletion curves (see Mayen and Soucail, 2000 (astro-ph/0003332) for a complete description of the code), we propose to constrain the mass profile of the cluster and the main characteristics of its potential (orientation and ellipticity). This application is based solely on deep photometry of the field and does not require the measurement of the shape parameters of the faint background galaxies.
