Enter at least the limits in longitude, those in latitude are optional. The default selection is based on the criterion l < 10°. You can refine the selection limits afterwards. If the scale is large enough, you can also choose to display the cluster names or not. The default is not selected.
The map is active and you can click on any cluster to obtain more information and links to other maps. The circle sizes are function of the cluster diameter. The colors code roughly the cluster ages.
