A Long-Term Study of Broad Emission-Line Profile Variability in NGC 5548
I. Wanders and B.M. Peterson: 1996, ApJ, 466, 174

Due to a minor error in one of the computer programs used, the emission-line fluxes tabulated in the paper are too low. All emission-line fluxes should be multiplied by the integer number 2; the continuum fluxes are correct. None of the conclusions is affected since the paper is based on relative fluxes only, but the following adjustments to the tables and figures should be made:

• Table 1: The numbers in columns 4, 5, 7, and 9, labeled L_tot, L_blue, L_core, and L_red, respectively, should be multiplied by 2.
• Table 2: The numbers in columns 6, 7, and 10, labeled < L(t) >, \sigma_l, and Phi, respectively, should be multiplied by 2.
• Table 5: The numbers in column 2, labeled Phi(total), should be multiplied by 2.
• Figure 1: The numbers along the y-axes of the 2nd, 3rd, 5th, and 7th panel, labeled total Hbeta flux, blue wing Hbeta flux, core Hbeta flux, and red wing Hbeta flux, respectively, should be multiplied by 2.
