Scientific paper

In the paper A Long-Term Study of Broad Emission Line Profile Variability in NGC 5548 by Ignaz Wanders and Bradley M. Peterson (ApJ, 466, 174 [1996]), the tabulated emission-line fluxes are too low, as the result of a minor error in one of the computer programs used. All emission-line flux should be multiplied by the integer 2; the continuum fluxes are correct. The conclusions of the paper are not affected by this error since its results are based on relative fluxes alone, but the following adjustments to the tables and figures should be made: Table 1: The numbers in columns (4), (5), (7), and (9), labeled Ltot, Lblue, Lcore, and Lred, respectively, should be multiplied by 2. Table 2: The numbers in columns (6), (7), and (10), labeled "," " 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 second, third, fifth, and seventh panel, labeled "total H beta flux," "blue wing H beta flux," "core H beta flux," and "red H beta flux," respectively, should be multiplied by 2. The corrected tables can be obtained at http://www-astronomy.mps.ohio-state.edu/~agnwatch/.
