This document provides information on EMCAL SuperModules layout seen from the back/magnet side, towards IP, with detail on sector arrangement and coordinate system according to ALICE-INT-2003-038. It includes rotational and linear numbering for sectors, ideal for LED amplitude plots. Standard view with row as Y-axis and column as X-axis. Detailed view from bottom of CalFrame available as alternative. Coordinates for SM and mapping provided.
