Fig. 2

Colour-coded λ21 cm polarised emission (on an absolute zero-level) observed with the Effelsberg 100-m radio telescope. The angular resolution is 9.′4. Overlaid contours show λ21 cm absolute total intensities starting at 3.8 K Tb in steps of 100 mK Tb. The bars are in E-field direction, and their length is proportional to the polarised intensity.
