Arrangement of elements in LOFAR stations.

Station type LBA (No.) HBA tiles (No.) Baseline (km)

Core 2  ×  48 2  ×  24 0.1–1
Remote 2  ×  48 48 1–10 s
International 96 96  ~ 100 s

Notes. Arrangement of elements in the three types of LOFAR stations, along with their typical distance from the center of the array (baseline). In the Core and Remote stations there are 96 LBA dipoles but only 48 can be beamformed at any one time. For these stations, one can select either the inner circle or the outer ring of 48 LBA dipoles depending on the science requirements. The HBA sub-stations can be correlated, or used in beamforming, independently.
