The Poynting flux graphs (left and middle panels) and input energy density graphs (right panel) over time for the red noise driver (solid blue line, RN subscript) and the detrended driver (red line, DT subscript) relative to the non-driven case (ND). The Poynting energy density input at the approximate height of the transition region (z = 7 Mm) is also given for both drivers (dashed lines).
