                    CALCULATION GRID SYSTEM RECEPTOR DATA                          
                                                                                
                      {F5 displays units abbreviations}                            
                                                                                
  Receptor grid system is Rectangular or Polar (R/P) ------------------- = [R]  
  Receptor grid system length units (m,km,ft,yd,mi,etc.) -------------- = [m ]  
  Receptor grid system height or elevation units (m,km,ft,yd,mi,etc.) - = [m ]  
  Receptor grid X,Y origin ------------------- = [            ],[            ]  
  (Note: Origin is added to rectangular receptor points.)                       
  Add origin to source rectangular coordinates (N/Y) --------------------- [ ]  

  Enter zero or blank for flat terrain, Height of flag pole for all grid 
  coordinates, X for flag poles at each grid coordinate or C for complex 
  terrain at each grid coordinate (blank or 0/height/X/C) --- = [            ]  
                                                                                
  Grid system orientation angle {units (d,r)= [d]} ---------- = [            ]  
  (Note: Orientation angle is positive when positive Y axis points              
   east of north when viewed from the south.)                                   
                                                                                
  Generate receptor grid system axes (Y/N) ------------------------------- [N]  
                                                                                
  Delete current X,Y,Z grid system receptor points (N/Y) ----------------- [N]  
  Delete current discrete receptor points (N/Y) -------------------------- [N]
