In gamma-ray burst research, it is quite common to fit the afterglow light curves with a broken power law to interpret the data. We apply this method to a computer-simulated population of afterglows and find systematic differences between the known model parameters of the population and the ones derived from the power-law fits. In general, the slope of the electron energy distribution is overestimated from the prebreak light curve slope while being underestimated from the postbreak slope. We… CONTINUE READING
