Flare frequency distribution for all stars, single stars, binary stars, and stars in different evolutionary stages for both samples. Here, the power index value of alpha was obtained by fitting the energy greater than or equal to 1 × 10³⁵ (represented by red vertical dashed lines) erg using the MCMC method and the green error bars represent the statistical error obtained by taking the square root of the total number of flares in the corresponding energy range.
