Same as Fig. 4 for the next three vertical planes. In the l = 45° and l = 60° half planes (top and middle), the HI Hercules shell is indicated at the 60–150 pc distance derived by Lilienthal et al. (1992) for its low-velocity component. Such a location is in good agreement with the elongated feature at b ≃ 40°. The second component at 250 pc may correspond to the fainter distant feature in the l = 60° half plane.
