SYNOPSIS

SEISMIC UNIX NOTES SUILOG -- time axis inverse log-stretch of seismic traces

 suilog nt= ntmin=  <stdin >stdout                              



 Required parameters:                                           

        nt=     nt output from sulog prog                       

        ntmin=  ntmin output from sulog prog                    

        dt=     dt output from sulog prog                       

 Optional parameters:

 NOTE:  Parameters needed by suilog to reconstruct the  

        original data may be input via a parameter file.        



 EXAMPLE PROCESSING SEQUENCE:                                   

                sulog outpar=logpar <data1 >data2               

                suilog par=logpar <data2 >data3                 



        where logpar is the parameter file
