Best-fit SED models and photometric data of four randomly selected unobscured quasars. Blue triangles, green squares, and red circles denote the photometric data points of SDSS, 2MASS PSC, and WISE, respectively. Dashed red and dotted blue lines mean the reddened spectra of quasar and host galaxy, respectively, and solid black lines represent the best-fit SED models. The name of the randomly selected sample and their E(B − V) values measured from the SED fitting are presented on the top left and top right side of each panel, respectively.
