 Required parameters:                                      
 w=vector of input wavelet to be shaped                    
 d=vector of desired output wavelet                        
 dt=tr.dt     (if dt header field is not set, then dt is a mandatory   

 Optional parameters:                                      
 nshape=trace           length of shaping filter                 
 pnoise=0.001           relative additive noise level
