Iterative GLS for the five planet model. The top panel shows the GLS of the RVs (ESPRESSO and PFS after correcting for the instrument offset). The subsequent panels show the previous row minus the model of planet b, model of the GP, model of planet c, model of planet e, and model of planet d, respectively. The last panel shows the window function. The horizontal lines indicate the 10% (dashed line), 1% (dot-dashed line), and 0.1% (dotted line) FAP levels calculated following Zechmeister & Kürster (2009).
