Cases under study.
| Sample name | Photometric | Spectroscopic |
|---|---|---|
| limit | training | |
| Case 1: Optimistic | 1 | Subsample |
| Case 2: Fiducial | 1 | Compl. drop |
| Case 3: Mid-depth | 2 | Compl. drop |
| Case 4: Mid-depth Euclid | 3 | Compl. drop |
| Case 5: Shallow depth | 4 | Compl. drop |
| Case 6: Inhomogeneous spec | 4 | Inho. spec-z |
Notes. The photometric limit value corresponds to the column number of Table 1 whose magnitude limit depths are used to define each photometric sample. The spectroscopic training sample used to determine the photo-z can be a representative subsample, a sample with a completeness drop in mVIS, or a sample with an inhomogeneous spectroscopic redshift distribution as shown in Fig. 1.
