ADC_Keywords: QSOs ; Gravitational lensing ; Photometry Keywords: cosmological parameters - gravitational lensing: strong Abstract: We present accurate time delays for the quadruply imaged quasar HE 0435-1223. The delays were measured from 575 independent photometric points obtained in the R-band between January 2004 and March 2010. With seven years of data, we clearly show that quasar image A is affected by strong microlensing variations and that the time delays are best expressed relative to quasar image B. Description: Photometry of HE 0435-1223, as in Fig. 3 of the paper. The first column gives the Julian date and corresponds to HJD days. Columns 2-9 give the photometric measurements of the quasar components A, B, C and D respectively, with the corresponding error bars. The last column provides the name of the telescope used for each measurement.
