Top panel: soft flares (black) and their associated delayed signal (black) spectra unfolded against a reflection-dominated model: optxagn (dotted-dashed lines), a heavily absorbed cold reflector (dotted lines), and a slightly absorbed hot reflector (dashed lines). Bottom panel: same as above, but unfolded against a Compton-upscattering-dominated model: optxagn (dotted-dashed lines), a hot reflector (blue dashed line), and a hot Compton-upscattering model (dotted lines).
