Reconstructed images from the Sgr A full visibilities dataset using both a concatenated dictionary of the first eight Daubechies wavelets (right) and IUWT (left) wavelets for a single major iteration using a single-step method that reconstructs with V_ℒ ∪ V_ℋ. Provided below are the error images against the ground truth, which show that the Daubechies dictionary is able to better reconstruct the large-scale gas structures. We use a log₁₀ scale to better illustrate the structural differences for the error images.
