136 Seismic Imaging Figure 5.6 Inverted vp models (m/s); top: after 15 iterations with fmin = 30 Hz and fmax = 60 Hz; bottom: after 30 iterations with fmin = 30 Hz and fmax = 300 Hz, starting from the model on the top. As for Figure 5.5, the density model is not updated. Figure 5.7 Vertical selections across vp models (m/s), left, and impedance models ρvp (in 103 kg/s/m2), right, for x = 20, 27, 30, 40 and 45 m, from top to bottom, respectively. Dashed black line: initial model; dashed green line: intermediate model (Figure 5.6, top); solid red line: inverted model (Figure 5.6, bottom) and solid blue line: exact model. As for Figure 5.5, the density model is not updated.
