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.
