Notes. Long dashes indicate that this parameter was not used or not explored.

^(a)

The best-fit results with confidence intervals.

^(b)

The explored range of values.

^(c)

The explored number of discrete values.

^(d)

When the modelled GRaTer profiles steeply increase outward, the exact location of the inner cutoff does not significantly influence the results. See Sect. 3.1.
