The X-ray spaltral fitting and optical data for each object within Missing AGN sample. Objects order on the figure follows the Table 2. X-ray band fitting plot (Odd panels): the individual hard (2 − 10 keV) X-ray data has been fitted with a power-law model modified by absorption and we have added the soft component defined as the excess over an extrapolation down up to 0.3 keV of the best power-law model fitting to the hard X-ray band only for those objects where It was made possible by the statistics. Even panels: SDSS spectrum plotted as (log F_λ) in units of 10¹⁷ erg/cm²/s/Å. Note that, for two sources (163 and 335) we have not X-ray spectrum due to the low counts in the X-ray energy band.
