1.2 Requirements

Users interact with the CDS xMatch service through a Web application which should run fine on any recent Web browser having Javascript and cookies enabled.
This includes Firefox, Chrome, Opera, Safari and Internet Explorer 8+.

The service is open to anonymous users, but we encourage people to register to the CDS services, using the Register link at the top right of the Web page.

We might in the future impose different usage policies for the xMatch service between anonymous and registered users.

We remind you that your account can also be used for the CDS Portal and the CDS Annotations service.
