Description of the topological connectivity of the poloidal flux map critical points as an undirected graph.

time_slice(itime)/contour_tree/node(i1)AoS¶Set of nodes. […]
Set of nodes. A contour tree node is defined by its critical type and position within the poloidal plane. A critical type of 1 references an x-point whilst a critical type of 0 or 2 references an o-point. Both X-points and O-points are rarely coincident with nodes defining the poloidal upon which the poloidal flux map is defined. The order in which the critical points are stored in the nodes array of structure is only important for the primary plasma O-point and X-points. If present, the primary plasma O-point should be placed as the first element of the nodes array of structure. If present, the primary plasma X-point should be the second element in the nodes structure
