Distributions of the Pβ/Hβ luminosityratios of the red quasars (color-hatched histogram) and unobscured type 1 quasars (gray histogram). The blue and red histograms indicate the distributions of the extinction corrected and uncorrected Pβ/Hβ luminosity ratios of the red quasars, respectively. After applying the extinction correction, the Pβ/Hβ distributionof red quasars agree broadly with that of unobscured type 1 quasars, but with a much larger scatter suggesting that the extinction-correction prescription is not perfect.
