New models and systematics: definitions and testing

Brief descriptions of the most important features of the systematics and models used in the benchmark calculations are given in Section 5.1.3 for a better understanding of the results and analyses. Participants have also provided full accounts of their work in their individual contributions to this report, along with more detailed descriptions of the benchmark exercise and results. All participants contributed to the developments achieved during this CRP through fruitful discussions at project meetings, constructive critiques and the formulation of useful ideas towards the solutions of problems.
