Table 8
Fraction of outliers for the photo-z computed with Le PHARE (top) and DNNZ (bottom), split by area, with respect to the number of sources with spectroscopic redshift for which the two methods agree (first row) or disagree (second row), following the definition in Sect. 7.3.
| Outlier fraction | |||
| Le PHARE | In KiDS | Outside KiDS | |
| Le PHARE and DNNZ agree | 3.7% [99/2663] | 8.5% [107/1256] | |
| Le PHARE and DNNZ disagree | 49.9% [377/756] | 51.3% [284/553] | |
| DNNZ | In KiDS | Outside KiDS | |
| Le PHARE and DNNZ agree | 4.0% [106/2663] | 6.8% [85/1256] | |
| Le PHARE and DNNZ disagree | 56.1% [424/756] | 64.0% [354/553] | |
Notes. The table clearly indicates that when Le PHARE and DNNZ disagree, DNNZ has a higher fraction of outliers among the spectroscopic sample, while when the two codes agree, the difference in fraction of outliers is marginal. To define agreement, we used 1+mean (LePHARE,DNNZ). The small difference in the fraction of outliers for the two methods when they agree depends on how close they are to the real spectroscopic value.
