## Scopes As described elsewhere, scopes in gwrucio are used to describe the observing epoch (e.g., ER9, O2, postO2, etc) data is aquired from. Scopes must be created *prior* to any data registered to that scope. To create the ER9 scope: ``` $ rucio-admin scope add --account root --scope ER9 Added new scope to account: ER9-root ``` So scopes are associated with user accounts. Here, we are using the rucio root account.
