Layout of the augmented GRAPH array (not to scale). Each blue line in the EW arm represents a group of eight LPDAs in 90° orientation (w.r.t. the celestial north). In the NS arm, each blue line represents groups of eight LPDAs in 90° orientation, and each orange line represent groups of eight LPDAs in 0° orientation (w.r.t. the celestial north). The photograph of a small section of the south arm of the augmented GRAPH is shown in the upper right.
