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