Vconvert - Convert from one type of velocity to another
Convert one type of velocity function to another
Output fast axis; only can change if outpar != inpar.
Ignored if outpar = inpar.
see above

[1]oversampling rate (default is no oversampling)
[12]oversampling interpolator length oversampling used with inpar != outpar only.
[0.01] fraction of peak value at ends of gaussian taper on sinc interpolator for oversampling
[1] velocity
[2] slowness 3- slowness squared 4- velocity squared
[1] interval
[2] rms
[1] function of time
[2] function of depth
NOTE: Vrms(z) [type=2 and par=2] is not understood by this routine.
NOTE: oversampling may improve v(z)<=>v(t) conversion if velocity field contains high wavenumber components. It can introduce spurious high wavenumber jitter if the velocity field is smooth. Decreasing alpha may help. Use with caution!
