MUSE synthetic map and spectrum (line of sight shown in the Fig. 5). Left: the Fe XIX 108 Å line emission map as in Fig. 5. The emission is integrated over macro-pixels with a size of Δ_h = 0.28 Mm, Δ_v = 1.89 Mm (0.4″ × 2.7″) (exposure time: 30 s). Right: Fe XIX line spectrum obtained by integrating the emission along the volume marked in the map on the left (white solid lines, cross-section 5 × 5 Mm). The spectral bin is Δv = 80 km s⁻¹. We account for thermal, non-thermal, and instrumental broadening.
