Left: scatter plots of total integrated radiative losses versus deposited acoustic flux in the ROI of the October 3 data set. Top: h = 1000–1400 km, bottom: h = 1400–1800 km. Solid lines show average (red) and median (green) values together with red dashed lines of ±1σ. Right: density contours of the scatter plots. Contours for magnetic (red) and non-magnetic (black) areas are plotted separately at density levels of 0.03, 0.3, 3, and 30% of a common density maximum. Straight dashed lines represent the full balance of radiative losses by acoustic-flux deposit.
