HI absorption spectra in comparison with the ¹³CO emission spectra toward the newly identified a) Cloud A; b) Cloud B; and c) Cloud C, which are coincident in projection with the halo emission in G29.37+0.1. In all cases the dashed line indicates the HI absorption spectrum obtained toward the bright clump of each cloud, while the ¹³CO emission spectrum is traced by the solid line. The vertical dashed line marks the velocity of the tangent point. The horizontal, solid line indicates the rms noise in the absorption spectra of the HI. The three cases show similar spectral features, which allow us to locate these three clouds at its near distance, d_clouds ~ 5–6 kpc.
