Maps in Polar Coordinates

This form allows to plot the clusters as a function of their galactic longitude and distance from the Sun.

Enter at least the limits in Galactic Longitude, those in distance are optional. The default selection is based on the criterion d < 500 pc. 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.
