- Who has access to my proprietary data?
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
- How does this work?
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.
- I am a co-I on project X but I can't download my
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.
- I am the PI on project X, and have a student/post-doc not on
the original proposal. What do I do?
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
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.
- What about projects with complicated access rules (eg.
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
