GRRT images and corresponding emissivity and electron temperature distributions. First row: GRRT snapshot images for Sgr A^* with inclination angle i = 30° at t = 12 240 M from (a) the turbulence heating model, (b) reconnection heating model, (c) R-β model with R_h = 160, and (d) R-β model with R_h = 1. Second row: Corresponding 230 GHz emissivity (left) and electron temperature (right) distributions. The solid white contours in panels (e)–(h) represent the edge of the torus, which is the ρ = 0.01 contour. The dashed contour represents the high magnetization region with σ > 1, which is cutoff in GRRT post-process.
