Tsalmantza and I discussed how we might winnow down our list of potentially lensed quasars into a set of sensible targets for HST imaging. It is essential to look for marginal evidence of extension; that is, do the quasars depart from our expectation of point-source morphology. A more speculative path is to look at luminosity indicators: Are any of the quasars brighter than you would expect given line strengths and ratios, possibly indicating gravitational magnification?
