+<H3>What is the meaning of the image?</H3>
+The image is a representation of the first and second moment of the
+distribution of the pixel values. The first moment is the center-of-gravity
+of the distirbution, the major and minor axis represent the standard 
+deviation around the center-of-gravity (<i>width</I> and <i>length</I>). 
+The line represents an estimate for the distance of the center-of-gravity
+to the origin of the primary particle (<i>disp</i>). Due to the lack
+of more information, it is a very simple estimate using
+disp=1.42*(1-width/length).
