Notes. The table includes (1) name of the galaxy; (2) time of the last accretion (lookback time); (3) ratio between the mass of the satellite that merges and the host galaxy at the moment the satellite enters the virial radius; (4) ratio between the mass of the satellite that merges and the host galaxy at the moment of the merge (tjump). In the case of Artemis and Oceanus, the two events are labelled as a and b.
