Out-of-transit cross-correlated-functions. Top: average observed CCF (created from the three OOT CCFs) shown as the solid black line with the best-fitting model overlain as the grey dashed line. The surface area under the CCF was arbitrarily set to 1. All CCFs have been shifted into the stellar rest frame. Bottom: residuals between the OOT CCF and model. We also show the three epochs used to create our average out of transit CCF, i.e. the three last observations on the 4 August, 2020(Indexing started with 0). Shown as grey error bars is the scatter on the CCFs outside of the central peak, specifically ±15 km s−1, which we have binned to 1 km s−1 and scaled to get a . The binned and scaled errors are shown with red error bars, which are applied to all data points, but for illustrative purposes are only shown in the aforementioned range.
