Maximum power in the LSP, averaged over the realisations, vs. period range for the seven spectral types before (upper panel) and after correction (middle panel). The residuals are from the follow-up analysis for ΔT_spot1, the middle of the habitable zone, and 1 M_Earth (fitted planetary signal removed). The habitable zone for each spectral type is shown in the lower panel, which also indicates the colour code for each of them (from top to bottom in this panel: K4 to F6).
