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
