Wide Priority Classes, as used in the allocation of MSA slitlets (see Section 3).
| Priority | Redshift | F160W | Hα flux (erg s−1 cm−2) ( * ) | Other |
|---|---|---|---|---|
| 1 | – | – | – | (see Section 3.1) |
| 2 | z ≥ 2.4 | F160W ≤ 24 | log fHα < −16.9 | – |
| 3 | 1.5 ≤ z < 2.4 | F160W ≤ 24 | log fHα < −16.9 | – |
| 4 | z ≥ 2.4 | – | log fHα ≥ −16.9 | Coverage of Hα, Hβ, and [O III] in G235H or G395H |
| 5 | z ≥ 2.4 | – | log fHα ≥ −16.9 | Coverage of Hα in G235H or G395H (cf. Priority class 4) |
| 6 | – | – | – | Selected as an AGN (see Section 3.1) |
| 7 | z ≥ 2.4 | F160W > 24 | log fHα ≥ −16.9 | Coverage of Hα, Hβ, and [O III] in G235H or G395H |
| 8 | z ≥ 2.4 | F160W > 24 | log fHα ≥ −16.9 | Coverage of Hα in G235H or G395H (cf. Priority class 7) |
| 9 | 1.5 ≤ z < 2.4 | F160W ≤ 24 | log fHα ≥ −16.9 | Coverage of Hα in G235H or G395H |
| 10 | 1.5 ≤ z < 2.4 | F160W > 24 | log fHα ≥ −16.9 | Coverage of Hα in G235H or G395H |
| 11 | z ≥ 2.4 | F160W > 24 | log fHα ≥ −16.9 | (cf. Priority class 7) |
| 12 | 1.5 ≤ z < 2.4 | F160W ≤ 24 | log fHα ≥ −16.9 | (cf. Priority class 9) |
| 13 | 1.5 ≤ z < 2.4 | F160W > 24 | log fHα ≥ −16.9 | (cf. Priority class 10) |
| 14 | z < 1.5 | F160W ≤ 24 | log fHα < −16.9 | (Satisfies one or both of the quoted magnitude and Hα cuts) |
| 15 | z < 1.5 | F160W > 22 | – | – |
Notes. For a source that fulfills multiple criteria, e.g. a source that could be in priority class 4 or 5, the source is put into the highest possible priority class (class 4, in this case). Note that below a redshift of z = 2.4 we no longer have coverage of Hβ or [O III] in G235H.
