Program sfsmoothderLS | Convert input to its derivative using LS and shaping regularization
[SYNOPSIS]
sfsmoothderLS < DATA.rsf > MODEL.rsf dataout=DATA_OUT.rsf niter=100 rect#=(1,1,...)
[COMMENTS]
* applied to causint_lop d = L m

Takes: rect1= rect2= ...

rectN defines the size of the smoothing stencil in N-th dimension.

[PARAMETERS]
string  | dataout | = |   | 	optionally, output predicted data (auxiliary output file name)
int     | niter | =100 |   | 	maximum number of iterations 
int     | rect# | =(1,1,...) |   | 	smoothing radius on #-th axis
