Notes. Rows: (a) Plummer sphere parameters used to model the bulges and haloes of the progenitor galaxies, as a function of the considered morphological types: MBulge is the (stellar) mass of the bulge, MHalo is the total mass of the dark matter halo, while rBulge and rHalo are their corresponding effective radii. (b) Parameters of the Miyamoto-Nagai density profiles used to model the gaseous and stellar discs of the different progenitors: the sub-index ⋆ denotes the stellar disc, and the sub-index g refers to the gaseous disc, M is mass, a is effective radius, and h is the vertical scalelength. (c) Number of hybrid particles (initially fully gaseous), collisionless stellar particles, and dark matter particles used for each progenitor galaxy.
