Ten spectra collected from the SDSS archive for the soft X-ray Swift-XRT sources detected in the BAT positional uncertainty region of the 3PBC sources. The upper left spectrum (J0040.5+2542) and the upper middle spectrum (J0838.7+2613) correspond to quasars. We classified the upper right spectrum (J1041.2+0451) as a type 2 AGN. The second row shows spectra of type 2 AGNs (left and middle) and a quasar (right). The third row shows the spectra of a quasar (left), a type 2 AGN (middle), and a type 1 AGN (right). The last spectrum image on the bottom corresponds to a star-forming galaxy. The main spectral emission and/or absorption features are marked in each figure. We are reporting the SDSS spectra with the same redshift precision, since none of the fittings had warnings.
