Top: Dynamic spectrum of a type II burst on 2015 Nov 04 from 144 to 1000 MHz, showing fundamental and harmonic bands. The overlaid rectangles delimit parts of the fundamental (red) and harmonic (blue) band. Bottom: Dynamic spectra in the ranges delimited by the red (left panel) and blue (right panel) rectangles in the top panel. The frequency axes of the two plots have a ratio of 2:1. A reference profile (mean from 12:00 to 12:01 UT) has been subtracted.
