Technical description :
We have been monitoring the quadruply lensed quasar HE 0435-1223 since December 2003 with different telescopes in the R band (∼600-720nm). The resulting R-band light curves of the quadruply lensed quasar
HE 0435-1223, is displayed in Fig. 2 of the paper. The light curves are obtained using deconvolution photometry of images from 4 different telescopes (the ESO Euler 1.2m, the CTIO SMARTS 1.3m, the Mercator 1.2m and the Maidanak AZT-22 1.5m), for a total of 876 epochs. Several sharp quasar variability features strongly constrain the time delays between the quasar images.
