Relation between peak flare amplitude in the TESS band, ΔL_f,t, and SpT. The minimum value of ΔL_f,t that could be detected for each target is represented by a “_” marker. The gray dashed line marks the highest of the flare amplitude detection thresholds for all flaring stars in this sample of L_max,th = 3.4 × 10²⁹ erg s⁻¹ (see Sect. 4.4). The color code visualizes the expected correlation between L_qui,T and SpT.
