MUSE arc images and C IV system maps. Columns from left to right: Column (1): White-image stamps of the gravitational arcs. Column (2): $0\stackrel{″}{.}6\times 0\stackrel{″}{.}6$-binned spaxels with C IV detections, colored according to their significance (Sect. 3.2). Spaxel coordinates as in Figs. A.1–A.8. In both columns, the PSF is represented by the lower-right circle. Columns (3), (4), and (5): Absorber-plane reconstructed maps of equivalent width (W₀¹⁵⁴⁸), velocity, and absorption spread, respectively. In all panels, the scale is indicated. In Columns (2)–(5), the triangles indicate W₀ ≤ 0.2 Å (2-σ) non-detections.
