Applying PolConvert to EU-VGOS Data


  • Dr. Frederic JARON

Primary authors



VGOS data are observed and recorded in dual linear polarization. During the fringe-fitting process these two polarization directions have to be combined to Stokes I, taking into account the parallactic angle. Before the visibilites can be coherently added, the cross-polarization complex gains for each telescope have to be determined in a calibration step. In this talk I show how PolConvert can be used in practice to calibrate EU-VGOS data. PolConvert also transforms the visibilites from linear to circular polarization, which has further advantages for fringe-fitting. I will present recent results of applying PolConvert to short-scan EU-VGOS sessions.
