Notes. Δt and var vobs are the time span and variance of the RVs, respectively, while Δvobs is the total span of the RVs. 
is a uniform prior (discrete in the case of Np) with lower and upper limits; 
is a Jeffreys (log-uniform) prior with lower and upper limits; 
is a modified Jeffreys prior with knee and upper limit; 
is a Kumaraswamy prior with shape parameters α and β. See, e.g. Ford (2006) and Gregory (2005).
