3. For each model, the normalized distance of its parameter values to the base case is calculated. "Base case" means that all parameter values are equal to their base values (normalized distance is 0), while "limit case" means that all parameter values are equal to their limit value (normalized distance is 1). Details on the distance calculation can be found in SI Section 2.4.4.1. This metric is herein referred to as "development distance", since it is an indicator for the amount of technological development that is represented by a given model. Together, the datapoints map the entire trajectory from the state-of-the-art (base case) to future technologies (limit case). The Monte Carlo/development distance methodology is implemented in pyH2A.
