Long Baseline Imaging with LOFAR
In this chapter we focus on the calibration of International LOFAR, which includes the long baselines provided by international stations, to produce high-resolution radio images. The Very Long Baseline Interferometry (VLBI) techniques are explained, as well as the different steps required to properly calibrate a long-baseline observation at low frequencies.
This chapter and all the techniques and procedures described in it are based on the work and many useful contributions of the LOFAR long baselines working group. AIPS is produced and maintained by the National Radio Astronomy Observatory, a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
