Three representative examples of single pulses exhibiting extensive quasi-periodic microstructure (top row), low-level PC activity within long stretches of Q-mode emission (second row), low-intensity square-like pulses (third row), and extremely bright pulse components (bottom row) as observed in the PC and MP phase range. We display the pulse numbers in the top-right corner of the profile panels. The dedispersed dynamic spectra are saturated at the same intensity in each panel.
