Integrated intensity maps (5 km s^-1 wide) of the [CII] (colour scale) and [NII] (contours) lines in the top panels and of the CO(4−3) (colour scale) and [CI](1−0) (contours) lines in the bottom panels, tracing the molecular and atomic material towards the Arched Filaments E1, E2, W1, and W2 and the H Region as shown in Fig. 12. The red star shows the location of the Arches Cluster, while red squares show the positions of two CS(2−1) peaks shown in the work by Serabyn & Guesten (1987), tracing high density material. The solid straight line shows the position of the Galactic plane at b = 0°, with marks denoting a few Galactic longitude values for orientation. The central LSR velocity of the maps is shown in each panel.
