The Potsdam Open Source Radio Interferometry Tool (PORT)

Funding Information: Research development for PORT was funded partially by the German Research Foundation (ECORAS-2, SCHU 1103/7-2 and HE5937/2-2). K.B. was funded by the Deutsche For-schungsgemeinschaft (DFG, German Research Foundation)— Project-ID 434617780—SFB 1464 (TerraQ). M.H.X. was supported by the Academy of Finland project No. 315721. S.B. was supported by Generalitat Valenciana SEJIGENT program (SEJIGENT/2021/001). The PORT source code is based on VieVS@GFZ which itself is a fork branched off from VieVS in 2012. In addition, the code contains MATLAB® adaptions of a significant number of IERS library functions (Petit & Luzum 2010) and modified GNU Octave (Eaton et al. 2008; Hansen 2011) routines. Software routines from the International Astronomical Union (IAU) SOFA Collection were used.
