    The pulse height distribution (PHD) is a one-dimensional                  
    histogram, that bins each of the detected events (pulses) based on        
    their 'amplitude'. Detected events are those that are larger than         
    the discriminator setting, which is an analog (voltage) value. Of         
    the 16 PHD bins, both the top and bottom 3 bins don't get any             
    events (this is caused by the digitization of this amplitude              
    information), so only 10 bins contain non-zero values. The                
    sampling parameter interval is effectively unknown and somewhat           
    arbitrary anyway since only the relative shape and stability of
