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.
