D3A Dish Alignment Plan

It is important that the two dishes are aligned so that their elevation axes are parallel and point in an East-West direction. It is likely that the laser tracker will be used for this alignment. However, it is necessary to have an East-West reference for the tracker. One possibility is to use the Synthesis Telescope track, which is describe in D3aSite.
