Caption: Figure 5.
The parameter grid search results in a range of best-fitting x2 elliptical orbits for the star-forming ring. This figure shows (ℓ, b) (left) and (ℓ, v) (right) projections of the best-fitting parameters summarized in the right-hand section of Table 3. Blue colors indicate more likely near-sided positions, while red indicates more likely far-sided. The black star indicates the location of SgrA⋆. Marker colors correspond to their most likely posterior PPDF positions. Colored x markers indicate clouds that have NF distinctions based on their PPDFs, but are not included in the fitting procedure. Black x markers are clouds that are not included in the fitting procedure and for which a formal NF distinction is not shown, due to the limited data and association with the majority of CMZ data points. Gray background points correspond to the spectral decomposition of MOPRA HNCO data from J. D. Henshaw et al. (2016b). ID numbers for well-known clouds are noted in the top left panel.
