Notes. We list each of the proposal parameters, derived parameters, and parameters controlled by priors separately. (*) Assuming a zero bond albedo and efficient day–night redistribution of heat. (†)We use 
and
as proposal parameters but report ecosω and
e sin ω here for convenience.
(‡) Constrained by a Gaussian prior.
