Fig. 13.
Dynamic spectra of PSR B0809+74, in two 3 MHz wide bands, of a one-hour NenuFAR observation. The color scale indicates the pulse S/N ranging from blue (no signal) to yellow (high-S/N), which is heavily modulated due to diffraction in the ISM. The high-S/N “islands” are commonly referred to as scintles and provide information on the turbulent interstellar plasma.
