Rest-frame 1.3 mm fluxes for the triplet images (A/B/C) and the foreground galaxy (G).
| Date | Beam FWHM | σ | A | B | C | G |
|---|---|---|---|---|---|---|
| [arcsec2] | [μJy/beam] | [μJy] | [μJy] | [μJy] | ||
| 2015 July 19 | 0.39 × 0.33 | 11 | 1147 ± 7 | 261 ± 7 | 82 ± 7 | 329 ± 7 |
| 2020 March 16+17 | 0.85 × 0.65 | 8 | 335 ± 6 | 123 ± 6 | 73 ± 6 | 377 ± 6 |
| Magnification | – | – | 21.3 | 14.4 | 11.3 | – |
Notes. The fluxes are obtained from the visibility-plane modelling, rather than synthesised images shown in Fig. 1. The magnifications are adopted from Suyu et al. (2013). We do not include the ALMA flux-calibration uncertainty (≈5%), as it does not affect flux ratios measured for the same epoch.
