Composite plot of h’f versus UT. (a) Bold lines are for CPN. (b) Thin lines are for BCL. (c) Dashed lines are for h’F(2.5 MHz). The occurrence of the highest order nF in ionograms are indicated by the blue-filled curve at the bottom of the figure. Three horizontal lines are shown to indicate presence of the 1F, 2F and 3F traces
