eRASS1 catalogs column desciption. All errors are provided as 68% confidence intervals (1 − σ).
| Column | Units | Description |
|---|---|---|
| IAUNAME | String containing the official IAU name of the source | |
| DETUID | String unique detection ID | |
| SKYTILE | Sky tile ID | |
| ID_SRC | Source ID in each sky tile. Use SKYTILE+ID_SRC to identify the corresponding source products | |
| UID | Integer unique detection ID. It equals CatID×1011 +SKYTILE×105+ID_SRC, where CatID is 1 for the 1B detected Main and Supp catalogs and 2 for the 3B detected Hard catalog. | |
| UID_Hard | Hard catalog UID of the source with a strong association, or -UID if the association is weak. 0 means no counterpart found in the Hard catalog. Only in the 1B Main and Supp catalogs | |
| UID_1B | Main or Supp catalog UID of the source with a strong association, or -UID if the association is weak. 0 means no counterpart found in the 1B catalogs. Only in the Hard catalog | |
