Summary of image properties for images of Abell 2142.
| Telescope | Frequency | Robust | RMS noise | Resolution | PA |
|---|---|---|---|---|---|
| [MHz] | [μJy beam−1] | [arcsec] | [ ° ] | ||
| −0.5 | 7.5 | 10 | 0 | ||
| MeerKAT | 1283 | −0.5 ( † ) | 15 | 25 | 0 |
| −0.5 ( † ) | 55 | 60 | 0 | ||
| −0.5 | 80.3 | 10 | 0 | ||
| LOFAR | 143 | −0.5 ( † ) | 172 | 25 | 0 |
| −0.5 ( † ) | 285 | 60 | 0 | ||
Notes. Images marked with a ( † ) were produced after source-subtraction, with a combination of uv-tapering and image-plane convolution used to achieve the desired resolution. The quoted RMS noise values were derived as the average of several off-source regions in the vicinity of the phase centre.
