Notes. Gaia G-band magnitudes of the primary (G1) and secondary (G2, if multiple components are present) sources, as well as FMP, are present in the Gaia archive. J-band magnitudes are either observed or derived from Gaia BP and RP photometry, as described in the appendix of Scialpi et al. (2024). Texp × Nexp indicates the exposure time in seconds multiplied by the number of exposures for the MUSE observations. Separation and classification are derived from our analysis of the data. The separation (Sep) corresponds to the distance between the two components in case of a double system (lensed, dual or AGN+star), and to the radius of the Einstein ring in the case of a quadruple lensed system (indicated with *). The PA is the angle measured clockwise from north toward east, calculated from components A to B.
