Pathways properties for frame set #2.

The table shows the total number of frames in which a specific tunnel cluster was present, the average length and bottleneck radius and the throughput, i.e. the average of e-cost across all frames using the cheapest tunnel in each frame. Pathways are shown from highest to lowest average throughput; average values refers to total number of frames in which a pathways was existent. The last column summarizes the simulation(s) in which a given tunnel cluster was observable; systems for which the pathway was less important are shown in brackets.
