 SUHROT - Horizontal ROTation of three-component data                  

 suhrot <stdin >stdout [optional parameters]                           

 Required parameters:                                                  
    none                                                               

 Optional parameters:                                                  
    angle=rad   unit of angles, choose "rad", "deg", or "gon
    inv=0       1 = inverse rotation (counter-clockwise)               
    verbose=0   1 = echo angle for each 3-C station                    

    a=...       array of user-supplied rotation angles                 
    x=0.0,...   array of corresponding header value(s)                 
    key=tracf   header word defining 3-C station ("x")               

    ... or input angles from files:                                    
    n=0         number of x and a values in input files                
    xfile=...   file containing the x values as specified by the       
                "key" parameter                                      
    afile=...   file containing the a values                           

 Notes:                                                                
    Three adjacent traces are considered as one three-component        
    dataset.                                                           
    By default, the data will be rotated from the Z-North-East (Z,N,E) 
    coordinate system into Z-Radial-Transverse (Z,R,T).                

    If one of the parameters "a=" or "afile=" is set, the data     
    are rotated by these user-supplied angles. Specified x values      
    must be monotonically increasing or decreasing, and afile and      
    xfile are files of binary (C-style) floats.
