Exponentially decaying light curves of a flare in the MT. High- and low-energy luminosities ( _HE/ _LE = 10) are plotted (normalized to 1) for increasing t _lc. Solid lines represent _HE and dashed lines _LE. Colors represent t _lc at differing factors of t _f , where t _{f, HE} is normalized to 1. The dashed black line is the 1/ e decay time.
