Tycho SNR as observed with the LOFAR LBA. The LBA bandwidth was split to make these two images, centered at 48.3 MHz (left) and 67.0 MHz (right), each 18 MHz wide. The elliptical beam size is 41″ × 31″, with position angle 56^o, and the pixel size is 10″ for both maps. The local rms noise is 0.03 Jy bm⁻¹ for the 67.0 MHz map and 0.08 Jy bm⁻¹ for the 48.3 MHz map. The flux density scale in both maps is in Jy bm⁻¹.
