Mitigating Source Structure in Geodetic VLBI on the Visibility Level
VieSOFT subtracts source structure phases from VGOS visibility data right after correlation, making the data resemble point-source observations; tests show more compact images, better closure delays, and slightly improved geodetic residuals.
