Fig. 3
HARPS fluxes, (H + K)/(R + V), for the available observations of HD 1237. The blue and green vertical lines denote the beginning of each observed epoch. The x-axis contains the number of days since the Heliocentric Julian Date (HJD = 2 456 123.5) of the first observation (2012 Jul. 15). The last two data points of the first epoch are unevenly distributed (after the vertical black line). We estimate a 5% error in our measurements.
