 BHPFILL - Fill Holes in BHPIO Cube Dataset                    

 bhpfill fills missing traces in a BHPIO cube dataset by      

 borrowing traces to fill in each empty slot. As an alternative,

 traces with all zeros may be written to empty slots.          

 To fill each missing trace, multiple traces may be mixed via 

 inverse-distance weighting, or a single nearest trace can be used

 The type of search done to locate traces to be mixed can be  

 a nearest-trace search, or a 'circular' nearest trace search.

 In a circular search, the iline,xline of the current output location

 is used as the center point of a grid, in which each quadrant of the

 grid is bounded by the iline and xline. The nearest trace in each

 quadrant is used in a 4-trace mix.                           

 bhpfill filename=                                            

 Required Parameters: filename=name                           

                      name of BHPIO cube to be filled         

 Optional Parameters:                                          

  pathlist='name'.dat      File containing filename partitions

  verbose=0                Use verbose=1 for long printout    

  foldfile='name'_fold.asc Name of file output from foldfile option

                           of bhpreadcube. foldfile is used to locate

                           occupied bins in the data          

  mode=mix                 Normal operating mode is to build  

                           output traces by mixing input traces.

                           If mode=zero, bhpfill simply writes

                           traces containing valid headers and

                           all zeros for samples to each empty

                           cube slot.                         

  nmix=1                   Number of traces to mix for each output

                           location; default is to just get nearest

                           trace                              

  search=circle            Circle means use the nearest trace in

                           each quadrant surrounding each output

                           location.
