Comparison of 3D models for the LMC disc mid-plane based on the inferred spatial variations in the viewing angle. Left panels: Tilted ring model. Central panels: Inversion method to best fit the inferred viewing angle variations with the galactocentric radius R as a continuous surface. Right panels: Inversion method to best fit the inferred viewing angle variations with both the galactocentric radius R and azimuth ϕ as a continuous surface. Top panels (green): LMC Combined complete sample. Bottom panels (salmon): LMC Combined optimal sample. We plot a triad that displays the unit vectors in the following directions: W, N, and LOS, being the last the observer’s direction. In the (x, y, z) frame, those vectors are defined by (1, 0, 0), (0, 1, 0), and (0, 0, 1), respectively (see Fig. 11 of Jiménez-Arranz et al. 2023b.) A video of these LMC 3D models viewed from different directions is available online.
