Identify missing things for joint assessment (task 3.2)  done. Define next steps. Consolidate common findings (lead: Silke). In parallel: visually inspect cases with most significant changes; perform 'recommended analysis'. Prepare some further sensitivity studies (see next page; lead: Axel). Run additional sensitivity studies (maybe 5?). Plan summary report (and proposal for follow-up project?) and paper.
