Notes. All data of Band 9 are identical than Pérez et al. (2014). The parameters for SR 21 in Band 7 of the ring+vortex model are omitted because of the unphysical results. The errors from the MCMC calculations are much smaller than the spatial uncertainty from the observations (and therefore omitted), which is ~ 10% of the beam size (i.e. ~3 AU for SR 21 and ~4 AU for HD 135344B).
