325 MHz radio image of the Cygni SNR (G78.2+2.1). The numeric labels, and R1 and R2, identify the sources and the diffuse enhanced emission regions, respectively, that are discussed in detail here (see Table 1). The colour scale interval shown is (–48, +83) mJy beam^–1 to outline weaker features. The synthesised beam (11.95″ × 9.61″, -76.6°) is plotted at the bottom left corner. The rms, where the emission is lowest, is ≃0.5 mJy beam⁻¹.
