Notes. Column 2 lists the real number of stellar lines in the mask and the total number of line occurrences when order overlaps are included. Columns 3 and 4 give the average FWHM of the CCF and the velocity shift compared to the K2 CCF; errors represent their scatterin the sample. The last two columns list the rms values of the residuals to the orbit model and the classical Rossiter-MacLaughlin model.
