Scatter plot of solar flare peak flux and SWF duration for SWFs with the criteria of dfmin ≥ 2.5 MHz (blue lines), dfmin ≥ 3.5 MHz (light blue), and complete blackout (red) for a all cases, and cases with solar zenith angles of b 0–45° and c 45–90°. The solid lines show the median value of the solar flare peak flux in each duration bin
