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

摘要

A radio continuum survey at medium Galactic latitudes with the Effelsberg100-m telescope is being carried out at a centre frequency of 1.4 GHz in totalpower and linear polarization. Areas up to +/- 20 degree of Galactic latitudeare now being observed at a sensitivity of 15 mK TB total intensity and 8 mK TBin linear polarization with an angular resolution of 9'35. This paper describesthe observing and reduction technique applied which results in absolutelycalibrated maps. The methods are illustrated by examples of images from thesurvey.
