As only a few red giants are supposed to exhibit light curve modulations due to star spots, we use for this work the largest sample of identified red giants observed by the Kepler satellite so far. It is composed of 17,377 pulsating stars including those already known from previous works (e.g. Huber et al. 2010ApJ...723.1607H; Hekker et al. 2011MNRAS.414.2594H; Mosser et al. 2012A&A...537A..30M; Stello et al. 2013, Cat. J/ApJ/765/L41; Mathur et al. 2016, Cat. J/ApJ/827/50). Table 1 is giving the stars with validated rotation periods. Table 2 is giving the stars showing rotational modulation in their light curve, but probably due to pollution from a nearby star. (2 data files).
