Table: gogreen_dr1.clusters
(The bold columns are indexed columns)
| Column Name | Description | Datatype |
|---|---|---|
| cluster | Short name of each cluster. | VARCHAR |
| cluster_id | An integer which is used to identify the corresponding photometry. It is a unique number for each SpARCS and SPT cluster; it is 14 for all COSMOS clusters and 13 for those in the SXDF. | INTEGER |
| dec_best | Coordinates, in J2000 degrees, for the best estimate of the cluster centre. For the SPT and SpARCS clusters, this is the location of the BCG. For the COSMOS and SXDF clusters, it is the average position of members as described in §4.2.3 of The GOGREEN adn GCLASS Survey: First Data Release paper | REAL |
| dec_gmos | Coordinates, in J2000 degrees, for the centre of the GMOS spectroscopic observations (GOGREEN only) | DOUBLE |
| fullname | Longer format cluster name | VARCHAR |
| gclass_m1 | Name of each GCLASS GMOS mask, for N from 1 to 5, used to obtain spectra for this program. | VARCHAR |
| gclass_m2 | Name of each GCLASS GMOS mask, for N from 1 to 5, used to obtain spectra for this program. | VARCHAR |
| gclass_m3 | Name of each GCLASS GMOS mask, for N from 1 to 5, used to obtain spectra for this program. | VARCHAR |

| photoz_cat | Name of photometric redshift catalogue | VARCHAR |
| preimage | Name of the GMOS z-band image, or Subaru pseudo-image, used for mask design. Note the preimages were used for mask design but are not optimally reduced, specifically regarding sky subtraction and astrometry. | VARCHAR |
| ra_best | Coordinates, in J2000 degrees, for the best estimate of the cluster centre. For the SPT and SpARCS clusters, this is the location of the BCG.
