Program sfdipn | 3-D robust dip estimation by plane wave destruction with non-stationary smoothing. 
[SYNOPSIS]
sfdipn < in.rsf > out.rsf mask=mask.rsf idip=idip0.rsf xdip=xdip0.rsf both=n n4=2 niter=5 liter=20 p0=0. q0=0. order=1 nj1=1 nj2=1 drift=n verb=n pmin=-FLT_MAX pmax=+FLT_MAX qmin=-FLT_MAX qmax=+FLT_MAX eps=0.0f rect#= shift#=

The output is dimensionless (stepout in time measured in time samples).
