Change in the t_1/2 flare duration proxy with log g surface gravity, L luminosity, R radius, T_eff effective temperature, M mass, and [Fe/H] metallicity, for the Kepler 30 min sample of flaring stars from Paper I. Each dot represents the median t_1/2 value of the observed flares for a given star, and the corresponding dot size is proportional to the number of flares. The scale is shown in the upper left panel. The blue lines and shades show the running median and the 16th to 84th percentiles, respectively.
