**Table A.7:** Optical properties of the AGN of the present catalog (from the Optical Monitor data). The data refers to the magnitude averaged over the whole observation. Columns: (1) Source name; (2) V magnitude [543 nm]; (3) B magnitude [450 nm]; (4) U magnitude [344 nm]; (5) *UVW1* magnitude [291 nm]; (6) *UVM2* magnitude [231 nm]; (7) *UVW2* magnitude [212 nm]; The uncertainties in the parameter estimates are at the $1\sigma$ level and also include systematics.
