SUREDUCE - convert traces to display in reduced time

 sureduce <stdin >stdout rv=                         

 Required parameters:                                
      dt=tr.dt    if not set in header, dt is mandatory    

 Optional parameters:                                
      rv=8.0            reducing velocity in km/sec         ",   

 Note: Useful for plotting refraction seismic data.        

 Trace header fields accessed: dt, ns, offset              
 Trace header fields modified: none
