Scale height in the thin and thick radio disc as function of various galaxy parameters. In each panel, we show the data points for the thick disc as filled circles colour coded with star-forming radius. Also, the best-fitting line for the thick disc is shown. The individual panels show the scale height as a function of SFR (top left), SFR surface density (top right), mass surface density (bottom left), and the ratio of SFR-to-mass surface density (bottom right).
