Interpolation in $\theta$ space and the corresponding synthetic images. On the left, $\beta$ is calculated from the orange circle and nine different $\theta$ values are fed into the decoder to generate the corresponding synthetic images, highlighting the transition area between ${\text{T}}_1-\text{w}$ and ${\text{T}}_2-\text{w}$ $\theta$’s. In the center we display our 2D $\theta$ space, in which circles indicate $\theta$’s for ${\text{T}}_1-\text{w}$ images and diamonds indicate $\theta$’s for ${\text{T}}_2-\text{w}$ images, and colors correspond to sites. On the right, a $\beta$ is calculated from the center circle and nine different $\theta$ values are fed into the decoder to generate corresponding synthetic images. Synthetic images and the corresponding $\theta$ values are matched either by numerical (left sub-panel) or alphabetical (right sub-panel) indexes.
