Evolution of inferred stratified atmospheric parameters from the inversions of ROI A. The parameter maps for three values of log τ₅₀₀ = [−4.2, −3, and −0.1] are shown in the panels a, b, and c, respectively. The first, second, and third rows show the evolution of T, V_LOS, and V_turb. Panel d shows cross cuts along the depth of the atmospheres through the y-axis for two time steps as indicated. The x positions for these cross cuts are indicated by dashed blue lines in panels a–c. The contours in each panel show the pixels classified as CBGs, as shown in Fig. 2.
