Notes. For each indicator, we report (i) the earliest time at which the breakup transition is identified; (ii) whether the map is able to identify the reshaping behavior; (iii) whether the map provides a quantitative measure, and (iv) the quality of the measure, which is assessed by means of a quality index: 1 – poor, 2 – good, and 3 – great. The quality index is based on a qualitative assessment of the level of noise within the map and its stability in time, and it indicates whether the qualitative or quantitative information is clearly identifiable from the map. We remark that this table only reports a qualitative assessment and is provided only as a means of comparison to identify whether a combination indicator/metric works in the context of this study case. Times refer to the physical time of the simulated scenario, not to computational time.
