Optical photometry of the foreground lensing galaxy.
| Band | λ | mag | Flux density | Instrument |
|---|---|---|---|---|
| [μm] | [AB] | [μJy] | ||
| u | 0.36 | > 25.0 | < 0.36 | GTC HiPERCAM |
| g | 0.48 | 26.0 ± 0.3 | 0.15 ± 0.05 | ″ |
| r | 0.64 | 24.5 ± 0.3 | 0.63 ± 0.06 | GTC OSIRIS |
| r | 0.63 | 24.6 ± 0.2 | 0.53 ± 0.11 | GTC HiPERCAM |
| i | 0.77 | 23.8 ± 0.2 | 1.10 ± 0.22 | ″ |
| z | 0.91 | 23.1 ± 0.2 | 2.09 ± 0.42 | ″ |
| F110W | 1.15 | 22.3 ± 0.2 | 4.36 ± 0.88 | HST WFC3 |
| W1 | 3.35 | 19.4 ± 0.1 | 63.1 ± 6.1 | WISE |
| W2 | 4.60 | 19.2 ± 0.2 | 75.9 ± 15.3 | ″ |
Notes. Due to the contamination of a nearby point-like source, the WISE data were not considered in the derivation of the photometric redshift of the foreground lensing galaxy (see Sect. 4.2). The upper limit to the u-band flux density is given at a 3σ level.
