Table: gogreen_dr1.photo
(The bold columns are indexed columns)
| Column Name | Description | Datatype |
|---|---|---|
| b_tot | Total fluxes in b filter. See survey paper for derivation detail | DOUBLE |
| cluster | Name of the corresponding cluster, when there is an associated photometric catalogue. Objects in the COSMOS or SXDF photometric catalogues are identified with those labels, unless there is a GOGREEN spectroscopic redshift, in which case we use the name of the associated target. Note that SXDF49 and SXDF87 share a field, and are identified here only by SXDF49. Similarly SXDF76a and SXDF76b are identified here as SXDF76. | VARCHAR |
| cphotid | This is a unique identifier for each object in this table. The first digit identifies the source of the photometry (1: GOGREEN; 2: GCLASS; 3: UltraVISTA/COSMOS; 4:SPLASH/SXDF). The next two digits are the cluster_id column from Table 2. The remaining numbers are the PHOTID identifier in the main photometric catalogues | INTEGER |
