A 1.4 GHz radio continuum and polarization survey at medium Galactic latitudes: I. Observation and reduction technique

Abstract

A radio continuum survey at medium Galactic latitudes with the Effelsberg 100-m telescope is being carried out at a centre frequency of 1.4 GHz in total power and linear polarization. Areas up to +/- 20 degree of Galactic latitude are now being observed at a sensitivity of 15 mK TB total intensity and 8 mK TB in linear polarization with an angular resolution of 9'35. This paper describes the observing and reduction technique applied which results in absolutely calibrated maps. The methods are illustrated by examples of images from the survey.
