Morphology of several stellar flares observed in TESS (upper row) and HST-COS FUV (lower row). Upper row: Light curves obtained with TESS. The details of the observations for these flares can be found in Table A.1. In the panels, the labels 2MASS...036 and 2MASS...441 stand for 2MASS J02365171-5203036 and 2MASS J22025453-6440441, respectively. Bottom row: Light curves produced by integrating observed flux over the wavelength range in FUV with HST-COS. The details of the observations for these flares can be found in Table A.2. In the panels, the labels 2MASS...168, Karmn...+035, 2MASS...036, and 2MASS...441 stand for 2MASS J01521830-5950168, Karmn J07446+035, 2MASS J02365171-5203036, and 2MASS J22025453-6440441, respectively.
