Table 1.
Width of sources at 80% maximum intensity in the maps produced via the three imaging techniques.
| STIM | IMD | VISD | |
|---|---|---|---|
| θ | 2.4 ± 0.6′ | 0.6 ± 0.1′ | 0.6 ± 0.1′ |
| AR width | 4.0 ± 0.6′ | 4.1 ± 0.1′ | 4.3 ± 0.1′ |
| QS width | 13.0 ± 0.6 | 9.6 ± 0.1′ | 7.6 ± 0.1′ |
Notes. The table lists: standard interferometric imaging (STIM), image-differencing (IMD), and visibility differencing (VISD). The beamwidth (θ) for STIM is given in the direction of the minor axis.
