Systematic effects in LOFAR data: A unified calibration strategy

Abstract:

Context: New generation low-frequency telescopes are exploring a new parameter space in terms of depth and resolution. The data taken with these interferometers, for example with the LOw Frequency ARray (LOFAR), are often calibrated in a low signal-to-noise ratio regime and the removal of critical systematic effects is challenging. The process requires an understanding of their origin and properties.

Aim. In this paper we describe the major systematic effects inherent to next gener...
