Synthetic data: ground truth (top) and reconstructed images obtained using CLEAN (middle) and resolve (bottom) self-calibration. The circular 0.15 mas CLEAN beam is illustrated in the bottom left corner of the plot. The CLEAN image was masked at the lowest positive value. The unified color bar on the top of the figure shows an intensity range of the ground truth image, where maximum intensity is $I_{\max }^{\text{GT}}=209\text{\hspace{0.17em}Jy\hspace{0.17em}}{\text{mas}}^{-2}$, the minimum value is $I_{\min }^{\text{GT}}=137\text{μJy\hspace{0.17em}}{\text{mas}}^{-2}$. Maximum intensity values of reconstructed images are $I_{\max }^{\text{CLEN}}=34\text{\hspace{0.17em}Jy\hspace{0.17em}}{\text{mas}}^{-2},I_{\max }^{\text{resolve}}=111\text{\hspace{0.17em}Jy\hspace{0.17em}}{\text{mas}}^{-2}$ correspondingly.
