  1. p = probability, v = absolute value. Reference values from [6] or calibrated to match an observed pattern in the population modelled here (indicated by *, see [4]). Measures of precision could not be assigned to values that represent proportions. Sensitivity = ratio of the relative change in Tm to the relative change in parameter value.
