Table 1.
Number of VIPERS galaxies after each selection and for both fields.
| Field | VIPERS galaxies | 3.0 ≤ zflag ≤ 4.5 | Flag(Line)≥1111 | % of total |
|---|---|---|---|---|
| W1 | 57970 (+287) | 35221 (+152) | 3407 (+11) | 5.8% |
| W4 | 28112 (+243) | 16301 (+106) | 1371 (+6) | 4.8% |
| W1 + W4 | 86082 (+530) | 51522 (+258) | 4778 (+17) | 5.5% |
Notes. The numbers in brackets correspond to the secondary objects observed by VIPERS. The first column describes the field, and the second column shows the number of primary and secondary galaxies on that field. The third column shows the number of galaxies after the cut for the redshift range, while the fourth shows an additional cut for the quality of the line measurements. The last column presents the final percentage of the initial sample used for this work. The initial VIPERS galaxies sample (first column) is defined so that: (1) stars are removed; (2) galaxies have redshift measurements (1 < zflag < 29.5); and (3) the i-band flux of secondary galaxies respects the same constraint as target galaxies (17.5 < iAB < 22.5). This sample represents all of the potential galaxies that could have ended up in our final sample. See Guzzo & VIPERS Team (2013) and Scodeggio et al. (2018) for the explanation of the flag system.
