Same as the right panel of Figure 8, but now using transparent gray-shaded contours and black lines, overplotted on the overdensity contours obtained with UMS stars from P21, for comparison. The solar system is located at (X, Y) = (0, 0 kpc). The black cross shows the position of the Galactic center, while the gray-shaded ellipse shows the relative orientation of the central bar of the Milky Way, as described in the text. The meaning of the different labels is explained in the text. A Jupyter notebook and underlying datasets are provided on Zenodo to allow replication of this figure, doi: 10.5281/zenodo.22284576.
