Spectral properties of emission from Abell 1914 at 150 MHz to 610 MHz high-resolution (6″ × 6″) (left panel) and 150 MHz–610 MHz–1.4 GHz low-resolution 30″ × 30″ (right panel). In both figures, emission lower than 3σ has been blanked, where σ_{LOFAR150, 6 arcsec} = 175 μJy beam⁻¹, σ_{GMRT610, 6 arcsec} = 120 μJy beam⁻¹, σ_{LOFAR150, 30 arcsec} = 1500 μJy beam⁻¹, σ_{GMRT610, 30 arcsec} = 230 μJy beam⁻¹, and σ_{VLA1.4, 30 arcsec} = 51 μJy beam⁻¹
