Notes. Regions are numbered as in the images. ν is the average observing frequency, TI, P, and α are the average total intensity, polarised intensity, and spectral indices over the integrated area, FP is the average fractional polarisation calculated from P/TP, i the inclination of the regular magnetic field towards the observer, and z the assumed path length of the emitting medium. The most likely location of the detected structure is given in the last column.
