Pulse energy distributions of PSR J1842+0358 for MP (left) and IP (right), with single-pulse energies (blue and violet) and running-averaged pulse energies (green and brown). The same colours of the pulse energies corresponding to the bright groups as in Fig. 3 apply. The weak pulse energy distributions use the same but lighter set of colours. The two pulse energies are normalised by the mean MP energy. The vertical line indicates the cut of the two groups, of 1/3 bright and 2/3 weak pulse intensities (as described in Sect. 3.4.1).
