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)

This is a database of galaxy-scale gravitational lenses, listing their coordinates, their image astrometry, photometry and spectroscopic data and, for some systems, a list of references. The database is not complete, and some of the data are unreliable or out of date, so it is important to double check the information (A).

This presents a galaxy-galaxy lensing study using a database large enough to subdivide the foreground galaxy sample by various properties, and still obtain a high signal-to-noise measurement of the mass profiles. (A)
