2. Select an overlay from the list.
The menu also shows the site IDs for which the overlay is valid.
If you try to display a product with an invalid overlay, IRIS displays the message,
Overlay origin more than 1000 km from radar location (1000 km = 621.4 mi). If
you get this message, check that the correct overlay is assigned to the radar site.
