Caption: Figure 9.

Transient phase space figure for PSR J2108+5055 in comparison to other transients. PSR J2108+5055 reaches a spectral luminosity similar to that of intermediate SGR 1935+2154 bursts. Figure adapted from K. Nimmo et al. (2022). Sokolowski+ (M. Sokolowski et al. 2025) represents the brightest detected Crab giant pulse at 215 MHz. Cordes+ (J. M. Cordes et al. 2004) represents the brightest Crab giant pulses detected at 430 MHz. The widths of Crab giant pulses at low frequencies are inflated due to scattering.
