Top panel: light curves for different cases in the 1−25 keV range. The cases represented are the standard case, a non-conductive case, a low-twist case, a case with a flux-rope twice as thin, a case with a flux-rope twice as long, a strong B-field case (twice as strong), and a case with strong B-field and a denser flux-rope such that the plasma beta and characteristic Alfvén speed are maintained (see the inset legend). Bottom panel: the same light-curves but with rescaled time and photon flux. The highest emission is approximately proportional to (product of the initial magnetic energy and the initial density) for each case. The time-scale to attain the emission peak is proportional to r₀/v₀ (ratio of flux-rope radius to characteristic Alfvén speed).
