double redshifts

Tsalmantza and I spoke about our multiple-redshift search in the SDSS spectroscopy. The new technology we bring is a data-driven model of the spectra; the goal is to increase the number of known lenses. We discussed tests of the model, and the hope that increasing the precision of the model will increase the sensitivity of the system to second (and third) redshifts.
