List of pre-pollution
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.
