When ready start Topcat or Aladin and Skychart, be sure the SAMP connection between the two is active using the menu menu View / SAMP / SAMP Status.
If not use the menu View / SAMP / Connect to SAMP hub.
Open the page http://exoplanet.eu/catalog/ in your web browser.
On the row “VO CONNECTION” click the “ON” button.
That's all, the exoplanet catalog is now installed in Skychart.
The stars with an exoplanet are marked on the chart with a red square and you can search for a planet name from the search bar. All the information are show in the detail window.
You can now use this data offline without the need to be connected to Topcat or the web page.
As exoplanet data are updated frequently you can update the data in Skychart simply by repeating the procedure above.
You can also use all the Topcat power to make data selection and send it to Skychart. See this example for more details.
The catalog display can be changed from the menu Setup / Catalog / VO Catalog
Click the button “Update” to make change.
