Long-term lightcurve of ɛ Eri starting from 2002. The binned Ca II S-index data are plotted with star symbols. The X-ray fluxes are overplotted as red squares. The filled squares refer to the X-ray fluxes calculated over the complete lightcurve of each observation. For those observations with a flare-like short term variability, the X-ray fluxes are also calculated after the removal of the flare and shown as open squares.
