 BHPINTEGRATE - Calculate the area of a peak or trough                

                at a user-specified time                              

 bhpintegrate < stdin > stdout [options]                              

 Required Parameters:                                                 

  None                                                                

 Optional parameters:                                                   

  mode=point   point: Get Z from header, find P1,P2                   

               edge: Get P1,P2 from header, find Z                    

 Z=sut         Trace header containing peak/trough time(ms)            

 A=d2          Trace header in which to store calculated area         

 L=f1          Trace header in which to store width(ms) of peak/trough

 H=f2          Trace header in which to store amplitude at peak/trough

 P1=igc        Trace header in which to store point m1 (ms)           

 P2=igi        Trace header in which to store point m2 (ms)           

 P3=corr       Trace header in which to store peak/trough point (ms)  

 type=peak     peak or trough                                          

 search=3      In point mode, the number of samples to search each side

               of Z to insure peak or trough is found                 

               In edge mode, the number of samples to search each side

               P1 and P2 to insure min or max is found                

 limit=25      Maximum distance to search each side of peak/trough    

               for an upturn or downturn                              

 enforce=yes   Ensure that upturns are negative for type=peak, and that

               downturns are positive for type=trough, unless the limit

               number of samples have been reached on an edge search  

  nval=-999.25 Z NULL value; set L, A to zero                         

 Notes:                                                               

  The limit parameter is unused in edge mode. Once the edges          

  are found, the peak or trough is found as the maximum/minimum       

  within the edges. Also, in edge mode, if search=0, then the edges   

  are taken exactly as given in the P1, P2 trace headers.
