Save data

The CDS Portal provides each user with a personal storage space where he/she can:

You do not need to register to be able to save results in your storage space, but we do recommend to register as:

  • Registered users are allowed to save results up to 500MB, whereas anonymous users can only save up to 100MB
  • Anonymous users are identified through a browser cookie. That means you will not be able to access your saved data from another computer (or even from another browser on the same computer).
    It also means that emptying your browser cache might remove the portal cookie, and you won't be able to access your saved data anymore.
    Registered users are identified through a login/password mechanism which allows them to access and retrieve their data from any computer.

Please read and acknowledge the CDS Portal guidelines before using your storage space.

Upload a list of positions

Lists of positions can be uploaded to your storage space, provided they are in VOTable format.
Tip:If your data is not in VOTable format, do not panic. You can easily convert it to VOTable using TOPCAT, a powerful table data editor and visualizer developed by Mark Taylor.

In order to upload your list of positions, point your browser to http://cdsportal.u-strasbg.fr/myData.html and click on Upload:
Upload button
This will show the following window: Upload window
Click on Browse, select the file you wish to upload, optionally enter a target name and a comment, then press Upload.

When the file is fully uploaded, it will appear in the list of your saved data.
