[en] We have been monitoring the quadruply lensed quasar RX J1131-1231 since December 2003 with different telescopes in the R band (~600-720nm). The resulting R-band light curves of the quadruply lensed quasar RX J1131-1231, is displayed in Fig. 4 of the paper. The light curves are obtained using deconvolution photometry of images from 3 different telescopes (the ESO Euler 1.2m, the CTIO SMARTS 1.3m and the Mercator 1.2m), for a total of 707 epochs. Several sharp quasar variability features strongly constrain the time delays between the quasar images.
