Caption: Figure 2.
Lags as a function of wavelength in the rest frame of NGC 4395, from the combined Night 1 + Night 2 data. Horizontal error bars denote the width of each filter. The β = 4/3 power-law fit to the riz data points is shown as a red curve. Blue dashed and dotted curves represent SSD lag–wavelength models calculated for BH masses of 1.7 × 104 and 4 × 105 M ⊙, respectively.
