From top: a) Cumulative frequency distribution of flare peak X-ray flux, f_X,peak, for the CVS serendipitous-stars sample: black solid line – “raw”, measured distribution; black dashed line – model distribution from ML power-law fit to raw, measured distribution; red solid line with dots – coverage-corrected “measured” distribution; red dotted line – model distribution from ML power-law fit to corrected distribution; blue dash-dot line – model distribution from ML power-law fit to corrected distribution, with higher minimum flux, f_X,min. Each model distribution has been derived from the data over the flux range indicated by the model (power-law) line. b) As a), but for the CVS target-stars sample, raw, measured distribution.
