Fig. A.4


Rayleigh statistic Z, as defined in Eq. (A.9), for the relative orientation angles ϕ calculated between HI and 13CO velocity-channel maps in the range 30 < vLSR <60 km s−1. The contours represent the 3σZ and 4σZ contours, where σZ represents the standard deviation of Z within the indicated velocity range.
