Row 1: the results of cross correlating our night 1 data with the Fe model. The location of the peak Kp and RV values are indicated by converging dotted white lines in each plot with a significant detection. For plots without a significant detection, the expected planetary signal location is indicated by nonconverging dotted white lines (i.e., RV = 0 km s−1; Kp ∼ 176.5 km s−1). The color bars indicate the significances of the maps, determined via dividing out the standard deviation away from the peak signal, calculated via a 3σ-clipped map (see Section 5.1). Row 2: the same as row one, but for night 2. Row 3: the same as row 1, but for nights 1 and 2 combined, with each night weighted by its respective average SNR. Surrounding plots labeled “both” are slices of the 2D Kp−RV maps at the peak Kp and peak RV for the blue (blue line), red (red line), and combined (black line) results. The dashed black lines represent the combined peak RV and Kp.
