6 Final remarks

We described the observation and reduction technique for a sensitive 1.4 GHz continuum and polarization survey with the Effelsberg 100-m telescope. We illustrated by an example the absolute calibration of the total intensity Effelsberg data by making use of the 1.4 GHz Stockert survey and showed the effect on the Effelsberg polarization maps after adjusting the large-scale polarized emission with the Dwingeloo 1.4 GHz measurements.

The methods used and introduced in this work have been found to be appropriate to conduct a 1.4 GHz survey which is absolutely calibrated both in total and polarized intensity and corrected for instrumental polarization down to a level of 1%.
