Synthetic data: ground truth (top) and reconstructed images obtained using CLEAN (middle) and resolve (bottom) self-calibration. The restoring CLEAN beam illustrated in the bottom left corner of the plot is 0.5 × 0.2 mas, PA = −5°. All images in the figure were masked at 3σ_rms level of a corresponding image. The unified color bar on the top of the figure shows an intensity range of the ground truth (GT) image, where maximum intensity is $I_{\text{max}}^{\text{GT}}=209\text{\hspace{0.17em}Jy\hspace{0.17em}}{\text{mas}}^{-2}$, the rms noise level is ${\sigma }_{\text{rms}}^{\text{GT}}=1\text{\hspace{0.17em}mJy\hspace{0.17em}}{\text{mas}}^{-2}$. The noise level of the reconstructed images are ${\sigma }_{\text{rms\hspace{0.17em}}}^{\text{CLEAN}}=3\text{\hspace{0.17em}mJy\hspace{0.17em}}{\text{mas}}^{-2},{\sigma }_{\text{rms\hspace{0.17em}}}^{\text{resolve\hspace{0.17em}}}=2\text{\hspace{0.17em}mJy\hspace{0.17em}}{\text{mas}}^{-2}$. Maximum intensity values are $I_{\max }^{\text{CLEAN}}=10\text{\hspace{0.17em}Jy\hspace{0.17em}}{\text{mas}}^{-2},I_{\max }^{\text{resolve}}=111\text{\hspace{0.17em}Jy\hspace{0.17em}}{\text{mas}}^{-2}$ correspondingly.
