Image mosaic of the 10 Chandra observations of the Bullet field in the 0.5–7 keV energy range (see Fig. 1). The green circles are centred on the main cluster and have increasing radii of 0.66 × R₂₀₀ and R₂₀₀ (see Fig. 1). The points of different colours correspond to sources selected from different catalogues with a measured VIMOS redshift: green circles indicate Chandra sources; cyan circles represent WFI sources; and red circles show IRAC sources. The black squares identify the sources with redshifts z ± Δz = (0.296 ± 0.014), corresponding to that of the Bullet cluster. The blue diamonds identify Chandra sources with redshifts, taken from the literature, in the interval z ± Δz = (0.296 ± 0.014).
