|Revisiting SEP tour with Madagascar and SCons|
The next example applies a simple constant-velocity NMO correction to the windowed data and pipes the result to a wiggle plotting command:
Running scons -Q nmo.view produces
< windowed.rsf /path/to/RSF/bin/sfnmostretch v0=2.05 half=n | /path/to/RSF/bin/sfwiggle pclip=100 max1=0.6 poly=y > Fig/nmo.vpl /path/to/RSF/bin/sfpen Fig/nmo.vpland Figure 6. Note that SCons does not recreate the windowed.rsf file if that file is up to date. You can experiment with the NMO velocity (2.05 km/s) or with plotting parameters to get different results. As Dellinger and Tálas (1992) point out, the NMO velocity of 2.05 km/s ``appears to split the difference between two distinctly non-hyperbolic shear waves''.
