Relevant parameters of recoiling and dual SMBH models for CID-42, along with the parameters inferred from observations (FC10, FC12). vk denotes the total kick velocity imparted to the merged SMBH for the recoil models; all other quantities are calculated at the time of observation (tobs). The galactic Lbol and L24 μm for each model are obtained from radiative transfer calculations with sunrise. For the dual SMBH model, MBH and Lbol, BH are given for each SMBH. The MBH and Lbol, BH estimated for the SE optical source in CID-42 (FC10) are given in the last column.
