Left: scatter plots of total integrated radiative losses versus deposited acoustic flux for the range h = 1600–1900 km in the ROIs of December 11 (top) and June 6 (bottom). 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.
