Fig. 3.
Correlation of Hβ line luminosity (upper panel), optical spectral index (middle panel), and NTD (bottom panel) with L5100 during the monitoring period. The empty squares are the epochs with NTD < 2, while filled circles are those with NTD ≥ 2. The dashed and dotted lines represent NTD = 1 and 2, respectively.
