Emission-line maps for the most important lines observed with VIMOS-IFU. From top to bottom and left to right, they are [Ar iv] 4711 Å; [Cl iii] 5537 Å; H_β; He i 5876 Å; He ii 4686 Å; [N ii] 6584 Å; [O iii] 5007 Å; [O iii] 4363 Å; and [S ii] 6731 Å. The orientation in the sky and the plate scale is the same as in Fig. 1. The intensity scale is normalised to the maximum value for each emission line.
