Left: Phase folded flux of binary A after subtraction of eclipsing model for ephemeris T_{0,  perpass} = RJD59995.6424 + 8.23459 × E. Maximum of flux occurs shortly after the periastron passage. Right: Light curve of binary B from TESS without heartbeat from binary A. Ephemeris of T_{0,  supconj} = RJD58627.15594 + 5.8528657 × E is used. Both available sectors 12 and 65 were used in all plots and are normalized to the median value per sector.
