Polar periodogram representation of LBL RV time series for HD 10700. The polar periodogram is focused at 1 year and represents the Pearson coefficient with a 1-year sinusoid as radial coordinates (see the main text) and the phase of the signal as the polar angle. Among the 3770 stellar lines, the numbers of lines presenting a Pearson coefficient higher than 0.4 are, respectively from top left to bottom right: 339, 59, 15 and 0. Top left: input dataset without any YARARA correction. Top right: dataset after YARARA flux correction. Bottom left: dataset after the LBL morphological corrections. Bottom right: dataset after lines with a significant 1-year power are rejected. Most of the 1-year-affected lines have been cleaned out.
