Sample uv coverage plots (left) and synthesized beams (right) including all present and planned LOFAR stations. The uv coverage is calculated for a source at declination 48°, and covers a 6 h track between hour angles of approximately − 3 to +3 hours. One point is plotted every minute. Synthesized beams are calculated using uniform weighting, and using multi-frequency synthesis over the full LBA frequency range from 30–78 MHz. The top frames are for the 24 core stations only, middle frames include all 40 core and remote stations, and the bottom frames include all 48 core, remote, and international stations.
