Notes.

(†)

Missing upper uncertainty limit reflects the fact that the bestfit parameter is found at the limit of the searching range.

(‡)

Given the parameter degeneracy between RB, AH, Td and Rd, we provide parameter ranges for which a similar-quality fit can be obtained . Values in parentheses correspond to the model shown in Figs. 6b and d.
