Description
A 15 by 15 grid of cells is indexed with letters representing columns, and numbers representing rows. Each cell is asymmetrical due to a marking at every grid bar intersection, similar to the centre marking detailed on the Centre/Rim Mark Specs page, allowing grid orientation to be determined at microscopic levels._x000D_
