Distributions of change in absorption peak (V_shift; Eq. (8)) for the subset of 228 pointings. Also shown are median and maximum V_shift per pointing. Two measurements at 150 and −180 km s⁻¹ have been excluded for clarity (see text for details). The error bars correspond to $\sqrt{count}$. Of interest is that the velocity distribution mainly extends out only to the intermediate-velocity (IVC) regime. LVCs and IVC are both objects of the infrared cirrus. This implies that they belong to the region below the disk halo interface (Crovisier et al. 1985).
