== My changes == 

 Some changes I've made: 
 # I've reduced the subheadings. A single subheading is not required. It spoils the ToC. I've promoted some lower level subheadings to top level headings.  
 #I've reduced the table width so that the image does not overlap in 800x600 resolution. 
 # I've used the main template 
 #Please use   between a unit and its number: eg 40 °C, it renders as 40 °C;  32 mm > 32 mm. It is part of the Manual of style. 
 # Page needs a copyedit.
