Long-term light variability of HD 116794, from Hipparcos and ASAS aperture-3 photometry. A smoothed spline for long-term detrending is shown in the ASAS panels. The data sets represented by “+” and “×” were shifted to 0.02 mag brighter magnitudes. Four ASAS measurements fainter than V = 9.76 (out of 657 data) fall outside the scale of the figure. Hipparcos data are represented by dots of different sizes depending on the number of observations (1, 2–3, 4–6) obtained within one day. Open circles refer to the two denser subsets discussed in the text.
