VLBI, fringe-fitting

Lecture at the GLOW interferometry workshop 18 November 2010 in Bonn

O. Wucknitz [1]

  1. AIfA, Bonn, Germany

Abstract

This tutorial shows how to do fringe-fitting with LOFAR data. Basis is a uvfits file that has been produced from LOFAR measurement sets. In the tutorial, fringe-fitting-solutions will be derived and applied with AIPS. This shows what can and what cannot be done with AIPS for long-baseline LOFAR observations.
