Detection limits in the SPIRou wPCA RV time series. The left panels show the upper limits on the semi-amplitude K in meters per second. The right panels display the limits in terms of the projected mass m sin(i). A zoom-in of the period range from 1 to 10 days is presented in the lower panels. Objects with a projected mass above the light blue and dark blue lines are ruled out with a confidence level of 99% and 75%, respectively. The red dot indicates the location of Gl 410b.
