Author contributions and equality statements All authors should have contributed to the manuscript substantially and have agreed to the final submitted version. The submitting author must provide an ORCiD when submitting a manuscript. We would be delighted if all authors provide an ORCiD upon acceptance for publication. This takes around 2 minutes per person to complete. Find more information here. Each author can claim one or more of the fourteen Article Author Contributions on the left, that are explained here in terms of the SCORO ontology. In the case of joint authorship, a numbered footnote should be added to the author listing, e.g. ‘X. Liu, Y. Sanchez and Z. Schwartz made equal contributions’ or ‘O. Mkwanza and P. Ollo jointly supervised the work.’
