Projection of the shell on the sky in Galactic coordinates. Assuming we are currently within the shell and that it has a thickness of 10 pc, the color shading gives the path length through the shell. The center of the shell is indicated by the × symbol. The minimum path length of 5 pc is along the radial direction from the shell center. The maximum path length (>50 pc) is seen along a thin ribbon tangent to the shell surface. The contours indicate directions in which ≥3 (gray) and ≥4 (black) local interstellar medium clouds are traversed along the line of sight based on the S. Redfield & J. L. Linsky (2008) kinematic model of the CLIC. There appears to be a spatial correlation between high path lengths of the shell model and regions with high numbers of local interstellar medium clouds, though it is not uniform around the ribbon. Such a correlation supports the idea that the origin of the CLIC is associated with a recent supernova shell.
