Pulse-energy distributions for the pulsar B0823+26. The vertical dotted line represents an integrated-intensity threshold of 0.10    ⟨ S ⟩ to distinguish the nulls. The upper panel presents the distribution prepared using data from Herfindal & Rankin (2009) and shows the observations at 327 MHz. The lower panel shows our observations at 8.35 GHz. Filled grey regions show the on-pulse energy, while the black contour plots the off-pulse energy. The offpulse noise is included for every pulse, but due to the large number of offpulse values near zero, their distributions were scaled according to the highest onpulse bin.
