Line 18:
* Minimum value (from every timestep) and the time of minimum
* Time series information - this can be slightly different from the results exported to the 'plot' folder as it will reduce the number of outputs to ensure it conforms with GIS attribute limits
=====Rules=====
The rules to categorise 'Likely Unstable' and 'Possibly Unstable' are very similar and the main difference is that they use different sensitivities. The parameters determining how sensitive each is can be modified by the user. The basic rules as follows, a more detailed description and how to change the sensitivity can be found further below:
* Rule 1: Flag as unstable if the minimum value is less than zero ''only applied to "Possibly Unstable"''
* Rule 2: Flag as unstable if the minimum and maximum values occur within a certain timeframe of each other
* Rule 3: Flag as unstable if the maximum value falls outside of the time series values by a certain amount
* Rule 4: Flag as unstable if the minimum value falls outside of the time series values by a certain amount
* Rule 5: Flag as unstable if a number time series 'bounces' with a magnitude greater than a given value exceed a given count
