FABBER Variational Bayes parameters, with their prior means and standard deviations, and the means and standard deviations used to initialize the approximate posterior. Mean values for $R_2^{’}$ and DBV are taken from Stone and Blockley (2017). Other model parameters are fixed to assumed values (Table 1).

Parameter	Prior		Initial Posterior
	Mean	Standard Deviation	Mean	Standard Deviation
DBV (%)	3.6	103/2	3.6	103/2
$R_2^{’}$ (s−1)	2.6	103/2	2.6	103
	500	103	500	103
