Notes.This model assumes the fifteen visible components shown in the second column, following Garbari et al., in which their disk mass model is taken from Flynn et al. (2006, the third and fourth columns). In this model, we adopt ρdm = 0.01 M⊙ pc-3 and derive hi (the last column) with MCMC calculation. Using the set of hi, the fifth column is recalculated by Eq. (8). Our assumed model of Eq. (6) uses the third and sixth columns. The uncertainties on σz,i(0) are set to be the same as in Garbari et al..
