 BHPTD - BHP Velocity Time/Depth Conversion                    

                                                               

 BHPTD      converts seismic data traces                      

            from time to depth and vice versa,                

            using velocities from a BHPIO cube dataset        

                                                               

 bhptd < infile > outfile [optional parameters]               

                                                               

 Required Parameters: none                                      

                                                               

 Optional Parameters:                                          

 verbose=0         Use verbose=1 for long printout            

 velfile=vels      BHPIO filename of velocity volume          

 pathlist=vels.dat BHPIO pathlist for velocity volume         

 type=time-depth   Conversion type; use depth-time for depth to time

                                                              

 ntout=            Number of samples per trace in output        

                   If not specified, ntout is set large enough to

                   map all samples in the first velocity trace  

 dt=0.004          Output time interval for depth-time conversion.

 dz=20.0           Output depth interval for time-depth conversion.
