Long-term photometric archival data of Wolf 327 from ASAS-SN (V band). Left panel: photometric time-series and best-fitted model computed using GP adopting a quasi-periodic kernel (black line). The 1σ uncertainty regions of the fit are shown in light blue. The residuals of the fit are shown in the bottom panel. Right panel: GLS periodogram (Zechmeister & Kürster 2009) for ASAS-SN V-band photometry. The vertical green line shows the fitted rotational period of the star. The horizontal lines represent the false alarm probability (FAP) levels of 10% (red dotted line) and 1% (blue dashed line).
