Sources have at least three outputs:
•Failed_Packages. This is the number of failed packages in the Source, and is dimensionless.
•Unexposed_Mass. This is a vector by species with dimensions of mass. It represents the mass of each species in the Source which is unexposed (i.e., still within unfailed barriers or undegraded matrix).
In addition, for every Inventory Cell specified, an output is created on the Source:
•Cumulative_to_Cell, where Cell is the name of the Inventory Cell. This is a vector by species, and has dimensions of mass. It represents the cumulative amount of mass of each species which has been exposed and placed into the Cell.
Note that this output is automatically linked into the Cumulative Input field for the associated Inventory Cell (and cannot be edited):
The Cumulative_to_Cell output of the Source element is linked into the Cumulative Input field in the input dialog for all Inventory Cells
