Table 2.
Forecast red quasars’ completeness (C) and purity (P) from NIR selection functions.
| Candidate red quasar selection function | C | P |
|---|---|---|
| HC1 > 0.6 and HC3 > −0.9 | 0.99 | 0.82 |
| J − Ks > 0.7, H − Ks > 0.3, | 0.99 | 0.79 |
| and i − Ks > 1.7 | ||
| HC1 > 0.3 and HC3 > −0.9 [Euclid-like] | 0.97 | 0.78 |
| YE − HE > 0.7, JE − HE > 0.3, | 0.98 | 0.80 |
| and IE − HE > 1.8 |
Notes. The first two rows report the selection function defined in the VISTA colour space, the last two refer to the reconstructed Euclid photometry.
