Sample of the study. Left: distribution of the stellar spectral type (color coded by the effective temperature). Right: period-mass diagram for all confirmed planets excluding those discovered by the imaging technique. Colored symbols correspond to the targets from our sample selected as explained in Sec. 2, where the color code indicates the effective temperature of the host star. The size of the colored dots informs on the number of RV measurements available for this work as indicated in the legend. The three horizontal lines show the masses of Jupiter, Neptune, and Earth for reference.
