Data collected across 5 independent sessions using two different FEI Titan Krios Microscopes, both equipped with a Gatan K2 Summit detector and volta phase plate. Volta phase plate used without charging between exposures. Phase plate evolution varied between different microscopes used to collect data but positions were shifted once phase evolution progressed past 120 degrees.
