“…In order to obtain a better value of this parameter, we applied seven different methods to recover photometric periodicities related to the stellar rotation period. We used quasi-periodic Gaussian Processes (QP-GP, see Damasso García et al 2014;Santos et al 2019), and the Gradient of Power Spectra (GPS e.g., see Shapiro et al 2020;Amazo-Gómez et al 2020a,b;Amazo-Gómez 2021). We applied those different methods (QP-GP, GLS, ACF, PS, and GPS) to analyze the combined, normalized, and stitched sectors 2 and 3 on TESS photometry (from 23 August 2018 to 17 October 2018, see Table 3.…”
