Notes. Rows: (a) characteristic parameters of the Plummer spheres used to model the bulge and the halo of the progenitor galaxies, for the different morphological types under consideration. (b) Characteristic parameters of the Miyamoto-Nagai density profiles used for the gaseous and stellar discs for the different morphological types of the progenitors. (c) Number of hybrid (initially gaseous), collisionless stellar, and dark matter particles used to simulate each progenitor galaxy, as a function of its morphological type.
