Biases per bin for redshift tomography defined on the mean spec-z of individual SOM cells.
| Bias (Δ⟨z⟩) | bin 1 | bin 2 | bin 3 | bin 4 | bin 5 |
|---|---|---|---|---|---|
| QC no | 0.197 ± 0.029 | 0.122 ± 0.057 | 0.127 ± 0.061 | 0.056 ± 0.038 | 0.032 ± 0.010 |
| QC yes | 0.087 ± 0.012 | 0.062 ± 0.008 | 0.084 ± 0.056 | 0.050 ± 0.039 | 0.034 ± 0.008 |
| Bias (Δ⟨z⟩) | bin 6 | bin 7 | bin 8 | bin 9 | bin 10 |
| QC no | 0.034 ± 0.012 | −0.013 ± 0.014 | −0.064 ± 0.018 | −0.122 ± 0.020 | −0.253 ± 0.034 |
| QC yes | 0.042 ± 0.009 | 0.008 ± 0.010 | −0.035 ± 0.013 | −0.079 ± 0.013 | −0.143 ± 0.015 |
Notes. The values listed are the mean biases over 100 different line of sight sub-samples, including the respective standard deviation. Under the recognition of QC, merely bin 7 comes close to sufficing the dynamic Euclid bias requirement of Δ⟨z⟩< 0.002(1 + z) when excluding standard deviations and considering the upper redshift bin limits from Table 2. The expression ‘QC’ refers to the consideration of quality control (see Sect. 4.3.3).
