Notes. All quantities are given in a reference frame whose origin coincides with the center of the MW-type galaxy, whose xy-plane coincides with the MW disc and whose z-axis is oriented as the internal angular momentum of the MW-type galaxy. The angles θorb and φorb, which indicate the orientation in this reference frame of the satellite orbital plane are given and expressed in degrees. The angles θsat and φsat give the orientation of the spin of the satellite galaxies. See Fig. 1 for a schematic representation of all these angles. Distances are in kpc, velocities are in units of 100 km s-1, and angular momenta are in units of 100 kpc km s-1.
