Relevant parameters of the total intensity and polarization images at a resolution of 19′′.
|Frequency||Orig. beam||Conv. beam||σI||σQ||σU|
|1443||16.8 × 15.2||19||0.34||0.12||0.13|
|1630||15.0 × 13.7||19||0.26||0.08||0.11|
|4535||19.7 × 15.3||19||1.50||0.11||0.11|

Notes. Column 1: observing frequency; Col. 2: original beam; Col. 3: smoothed beam; Cols. 4–6: RMS noise of the I, Q, and U images at 19′′ of resolution. We note that the noise levels of the images at 4535 and 4885 MHz contain the PB core correction, which is obtained with the task FLATN of three different pointings.
