NRAO Archive - Choose Account Service

Please choose the service you have an account with from the choices below.

What if I have an account with several services?

You may log in with either account. If you have an account with ALMA and the NRAO, you may link the two accounts at the ALMA login portal by going to your user profile and clicking the Account Linking tab. Once your accounts are linked, you may log in with either and you'll always see all your requests and all your proprietary ALMA and NRAO data.

If your accounts are not linked, you'll only be able to see your proprietary ALMA data when logged in with your ALMA account and likewise your NRAO data when logged in with your NRAO account. Requests you make when logged in to one will not be visible when you log in to the other.
