By default, you will have access to the proprietary data for every JCMT observing project on which you are a PI or co-I, provided that you have registered your CADC username with the JAC.

NB: CADC user names are free and last indefinitely, and you can check or update your CADC registration information at any time. If you have completely forgotten your CADC username or password, please contact the CADC Helpdesk.

Every successful JCMT applicant has an OMP user_id at the JCMT. If your user_id is linked with your CADC username, you will automatically have access to your data.

The list of users authorized to access proprietary data is automatically updated at the CADC once each day, so it can take up to a day after your CADC username is registered with the JAC to get access to your proprietary data.

The most common problem is that your CADC username is not linked to your OMP user_id. Please contact the support scientist for your project at the JCMT to register your CADC username. Note that you only need to register the CADC username, not your password! Also, registering your CADC username only needs to be done once, and will be applied to all projects past and future that use the same OMP user_id.

As the PI, you are the "Group Administrator" for your project. You can grant (or revoke) additional collaborators access to your project's data by selecting Edit Proprietary Access Control from the "Related Links" menu, provided you know their CADC usernames. This will prompt you for your CADC userid and password, then pop up a page listing all of the groups for which you are an administrator. The "Edit" button in the left hand column of this list opens an interface to edit the membership for each project group.

The PI and Co-Is in each project will already be members of the project group. They cannot be removed permanently through this interface, even by accident, because they will be restored to the group each day automatically.

In the event that the PI wants to delegate one (or more) people to manage access control for a project, they can contact their support scientist at the JAC to add additional administrators for the group. This will not simplify the access rules, but it will spread the burden!
