Distribution of southern MIVC± candidates at b< −20° on top of the inferred H2 column densities. The map is plotted in zenith-equal area projection centred on the southern Galactic pole with Galactic coordinates. The iso-latitude rings are placed at −20° with a decrement of −20°. All blue areas indicate positive NH2, all red negative NH2. The grey and black contours denote the total integrated (negative and positive) IVC H i gas at and 1.5 × 1020 cm-2, respectively, tracing the location of IVC complexes. The red and dark violet contours show the location of the inferred MIVC and MIVC+ candidates (Tables A.1 and A.2). The green diamonds indicate known high-latitude molecular clouds from FIR excess emission, the green squares show the positions of unidentified FIR excess sources as listed in Reach et al. (1998, their Tables 3 and 4).
