Revisiting 3C 279 jet morphology with space VLBI at 26 microarcsecond resolution

The International VLBI Service (IVS) organised the 13th biennial Technical Operations Workshop (TOW 2025) held from May 4 to 8, 2025, locally organised by MIT Haystack Observatory. TOW is, in practice, essential for operators and stations new to operational VLBI, whether in geodesy, astronomy, or both.

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.
