run##.***

There are seven files in this format for each run, each file being a copy of the appropriate run.## file as described above in section 4.12.5 (ie. one for each parameter). These files have to be stored (and not just the rundata.*** files) as it is possible to alter the contents of each file, for example by adding an outflow in such a manner that it is no longer possible to describe the parameter distributions using a simple equation.
