Table 2 Average Q values calculated by spectral ratio using pre- and post-NMO traces

From: Geophysical imaging of subsurface structures in volcanic area by seismic attenuation profiling

Depth	Pre-NMO	Post-NMO offset = 1 km	Post-NMO offset = 2 km	Post-NMO offset = 3 km	Post-NMO offset = 4 km
10 km	100.0	100.5	101.9	104.5	109.0
15 km	100.0	100.3	101.2	102.9	105.5
20 km	100.0	100.2	100.9	102.1	104.0
