Calculation will run with almost 2-fold (Dual Core) or 4-fold (Quad-Core) the speed.
Calculation will run up to 16-fold the speed. (Requires multiple networked sufficient PCs; Special Installation knowledge required.)

Consecutive number for internal use and quick reference.
For each receptor point collective a pre-pollution (v) for the annual average value (I1) and the short-time value (I2) can be entered. If at least one pre-pollution value is not zero, the log of the result will be extended to a table with pre- and total pollution.
When editing, the relation between pre-pollutions and collectives has to be considered.
