This IC project focus on the use of weak-lensing techniques for the determination of the mass-richness relation of galaxy clusters using the CS82 survey data. This is a crucial step towards the determination of cosmological parameters through galaxy clusters count. Recently this kind of calibration has been done by the use of the stacking of the lensing signal of multiple systems in bins of richness. In this project we intend to start the development of a method that precluded the binning, the simultaneous fit of all systems.
