Extracted spectra of the QSO 3C 196 and its DLA galaxy in the red channel of LRIS, which covers a rest‐frame wavelength range from 4700 to 6700 Å. The panels show spectra of the QSO, the galaxy plus the QSO, and the galaxy after subtracting the QSO contribution. The prominent emission‐line and absorption‐line features of the galaxy are shown with dashed lines, and emissions of the QSO with dash‐dotted lines. The broad feature near 7600 Å is caused by telluric absorption. Note that Hβ emission from the DLA galaxy is slightly offset from the [O II] emission of the QSO.
