摘要: We present a novel method to reconstruct the mass distribution of galaxy clusters from their gravitational lens effect on background galaxies. The is based least-χ2 fit two-dimensional cluster potential. combines information shear and magnification by designed easily incorporate possible additional information. describe technique demonstrate its feasibility with simulated data. Both morphology total are well reproduced.
