Mount Wilson S-indexes for Gl 729 derived from CASLEO (blue circles), HARPS (red triangles), FEROS (green diamonds), UVES (magenta stars), X-shooter (cyan cross), and HIRES (black inverted triangles) spectra. We highlight the CASLEO spectra where an increase in activity is observed with gray circles. We show the two observations we discarded from our analysis as dashed red circles.
