Hi brightness temperature distribution of two HT clouds associated with the LA4 are displayed in gray-scale on a linear scale. Both clouds show a cometary shape in this velocity channel of 84 km   s^-1. The contour lines mark Hi gas line temperatures at 100, 200, and 400 mK. The closest bow-like object connected with the head of one HT cloud is at v_GSR = 144   km   s^-1, and all the more distant structures are at v_GSR = 25   km   s^-1. The solid line marks the orbital motion of the MCS, the long dashed line the lagging rotating halo, and the short dashed line the projection of the resulting velocity vector.
