Serial MultiView: an efficient approach to mitigating atmospheric spatial-structure errors for VLBI astrometry

It is difficult for VLBI to perfectly correct atmospheric spatial structures, unless a close enough calibrator can be found, e.g., an in-beam calibrator. These errors could lead to lower SNRs and more artifacts for imaging, and position offsets for astrometry, up to milliarcsecond level at centimeter wavelengths.
