BTOR

Applies azimuth and vertical angles to geophone trace headers from a bhod.lst file. The command line arguments are:

 btor lstfil, prfx, isw1 maxtr
  
 lstfil  =input list file name (ex. bhod.lst) 
 prfx    =*.seg file prefix (one character) 
 isw1    =up/down switch 
       -1=apply to *.lst file and one less 
       +1=apply to *.lst file and one more 
        0=IF VERTICAL IMPACT source 
 maxtr   =maximum number of traces in shot record 
        6= 3 components down-hole, 3 ref-phone
        7= 3 down, 3 ref-phone, 1 load cell
  
  
 EXAMPLES: 
        [if file number (col. 1 of bhod.lst) is 005 
        and isw1=-1, the azimuth and vertical angle 
        also applied to file 004] 
  
        [if file is 005 and isw1=+1, azi and vert 
        applied to 006 also]

A summary of the flow is this:

• GENBHOD 10.1.9 creates bash scripts to run on down-hole data acquired from a horizontal component source, two blow orientations per subsurface station. The output is a file, bhod.lst.
• BTOR Reads the bhod.lst file and applies the determined phone orientations to the headers.
• GENBROT 12.2.3 creates scripts to run BROT.
• BROT 12.2.4 runs the script to actually rotate the data to a standard orientation.
