2D maps of Galactic [C ii] emission compared with that of H i and CO emissions in the spectral line data in the GOT C+ survey. Here we use all spaxels with distance estimates (see text). We use only intensities in the spaxels with H i, [C ii], or CO detections. The spiral arms are identified in the top left panel and S denotes the solar system. The circle (2 kpc radius) marks the Galactic center region. The void seen near the tangent points in all maps is an artifact resulting from the algorithm used to resolve the near- far-distance ambiguity (see text).
