Known LRDs from our BLAGN sample. Blue and red lines are the best-fit exponential (V. Rusakov et al. 2026) and Gaussian models, respectively. ﹩{\chi }_{r,G}^{2}﹩ and ﹩{\chi }_{r,E}^{2}﹩ indicate the reduced χ² of the Gaussian and exponential fits, respectively. A_G and A_E indicate the broad-line asymmetry, where a value of −1 or +1 indicates blue- or red-wing excess, respectively. The residuals are shown in the bottom panels, with the left and right wings indicated in green and orange, respectively. Overall, exponential models fit the line profiles better.
