Light curves of the rate phase-folded with a period of 1.205 days. The red dots indicate the 2013 observation, and the green and blue dots indicate the 2016 observation split in two periods. Phase zero was set arbitrarily to the beginning of 2013 observation. The three main peaks of X-ray emission can be put in phase with a period of 1.205 days, which corresponds to the rotational period of the star.
