    Spectrophotometric monitoring since 2013

FRODOSpec: lensed images within the FOV (January 6, 2014) and preliminary spectra at two different epochs  (November 7, 2013 & March 26, 2014)

SPRAT: preliminary spectra in 2015–2016

  New database for a sample of optically bright lensed quasars in the northern hemisphere (A&A)
