GLSP of the RV and activity indicators from ESPRESSO (a) and HARPS (b) data. The last row for both instruments presents the window function. The vertical dotted lines indicate from right to left the orbital period of the planets b, c, d, and e, the planetary candidate 05, and half and the full stellar rotation period (assumed here to be 80 days). The horizontal lines indicate the amplitude levels corresponding to 10% (dashed line), 1% (dot-dashed line) and 0.1% (dotted line) of the FAP. The amplitudes of the GLSP s are expressed using the ZK normalization described in Zechmeister & Kürster (2009, Eq. (5)). The FAP levels are computed using the analytical relation also described in Zechmeister & Kürster (2009) for this normalization. We display the GLSP of the BIS for completeness and comparison with C19, but we caution that the reliability of BIS measurements from CCF s for M dwarfs is uncertain (Rainer et al. 2020).
