 \bmad uses three coordinate systems as illustrated in \fig{f:coords}. First, the \vn{global} (also
-called ``\vn{floor}'') coordinates are independent of the accelerator. Thus such things as the
+called ``\vn{floor}'') coordinates are independent of the accelerator. Such things as the
 building the accelerator is in may be described using \vn{global} coordinates.
 
 It is not convenient to describe the position of the beam using the \vn{global} coordinate system so
