Particle background-subtracted and exposure-corrected photon image of TM 1, 2, 5, 6, and 7 in the soft band in logarithmic scale. Left: four sectors, SW, SE, NW, and NE out to r₂₀₀ (dashed white lines), are illustrated. These areas were used to extract the counts for the surface brightness profiles. Center: elliptical annuli (white) out to a semimajor axis of 19 and a semiminor axis of 9.5. The annuli have the same eccentricity and angle of 40 deg, which were chosen to be visually aligned to the cluster shape. These areas were used to obtain temperature, metallicity, and normalization profiles. Furthermore, the temperature map was determined within a circular area of 19 (magenta) to ensure enough counts in the source regions for spectral fitting. Right: calculated characteristic radii r₅₀₀ (green), r₂₀₀ (dashed white) and r₁₀₀ (yellow) of A3408 and A3407 from analyzing ROSAT data and applying the relations r₁₀₀ ≈ 1.36r₂₀₀ and r₅₀₀ ≈ 0.65r₂₀₀ in Reiprich et al. (2013).
