Abstract:
We present VRi photometric observations of the quadruply imaged
quasar HE0435-1223, carried out with the Danish 1.54m telescope at the
La Silla Observatory. Our aim was to monitor and study the magnitudes
and colors of each lensed component as a function of time.
Description:
Tables contain the light curves of the 4 components of the quasar, in
the V, R, and i bands.
