Panel a: dipole elements that make up UTR-2. UTR-2 consists of 2040 of these dipoles. In the N-S direction, 1440 elements are spread over 240 rows, while 600 elements are spread over the E-W direction giving the telescope a total area of ∼1.4 × 105 m2 (Konovalenko et al. 2016). Panel b: heart of the LOFAR core, known as the Superterp (Haarlem et al. 2013). The large central island in the photograph contains 6 of the 24 core stations, each of which includes a field of 96 LBAs and two sub-stations of 24 HBA tiles.
