GLS periodograms for 44 UMa of RV data, residuals after subtraction of the best fit, Hα index, window function, HIPPARCOS, and ASAS SN V-band and TESS photometry. The blue dashed line corresponds to the orbital period of the planet. The green dashed line corresponds to the upper limit of the stellar rotation period. The green area shows the minimum and maximum value that the upper limit of the stellar rotation period can have, given its uncertainty. The gray vertical dashed lines correspond to one-month (29.53 d) and one-year (365.25 d) periods. The purple dashed lines in the RV data GLS show the yearly aliases of the main peak. The horizontal red lines show the 10%, 5%, and 1% FAP levels.
