For the synthetic data in Figure 2, we show three one-dimensional profiles (panels (a)) comparing the data (thin line) and the model (thick line) taken at the location labeled “1,” “2,” and “3” in panel (b). Panel (c) shows a 3D representation of the data (blue) with the model overlaid (red) where we used two flux levels at 5 × 10−20 and ﹩1.5\times {10}^{-19}﹩ erg s−1 cm−2 Å−1. The cube orientation is shown, where the wavelength axis is the z-direction.
