    While not the first attempt at reconstructing extended lensed sources, this paper provides a good introduction to the topic: much of the galaxy-scale lens modeling work of the last decade builds on this paper. (A)

    The lens and source models are similar to GravLens, but exploration of the parameter space proceeds differently, to cope with the more complex cluster systems. The options are manual iteration (for which a graphical interface is provided), and Markov Chain Monte Carlo sampling. Weak lensing data can also be included in a joint fit. (A)

    This code provides an extensive range of simplyparameterized mass models, and a high-resolution lens-equation solver for precise pointlike image position, flux, and time-delay prediction. Likelihood maximization can be performed. (A)

    This paper investigates an error that pervades mass measurements with weak lensing, namely the assumption of a spherical mass model when fitting a non-spherical system. It gives theoretical expectations of the effect from N-body simulations and analytic tri-axial mass models. (A)

    The Master Lens Database http://masterlens.astro.utah.edu is the intended successor to CASTLeS: it contains much more extensive information (including lens model parameters) for a much larger, almost complete, sample of lenses. (A)

    A good qualitative summary of the methodology and results of weak lensing circa 2007, and is a good resource for a student wanting to learn about what weak lensing can tell us about cosmology without having to understand all of the math behind the models (I, A).

    This paper investigates an error that pervades mass measurements with weak lensing, namely the assumption of a spherical mass model when fitting a non-spherical system. It explores whether the departure from the expected concentrations of certain clusters is a result of this effect. (A)

    This paper describes measurements of cosmic shear from a 2 square degree Hubble Space Telescope survey, combined with photometric redshifts of the lensed galaxies. The addition of the photometric redshifts allowed the authors to measure the evolution of the mass power-spectrum, which provides additional information about the cosmological model beyond what the integrated power-spectrum can provide.
