Units of the circuitscape output

[Lindsay Hunt]

Hi, 

The group I am working with to create predictive connectivity maps has asked what the units of the output map are.

I understand that the final output from Circuitscape is a cummulative normalized current map from each of the pairs of focal nodes. I was wondering what the units of this output is? Do they have units or are they unitless? 

Thank you,
