The grouping is based on a range of characters including sedimentation coefficient, stabilization of the capsid, banding behaviour in Cs2SO4, protein subunit molecular weight and distribution of particles within the cell. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-36-2-289
