Flowchart representing the different stages of the process to determine the spatio-kinematic structure and mass-loss rates of the jet and the mass-accretion rates in the disk. Arrows indicate connections between the different steps. The first stage consists of the data collection and jet model (blue). The second stage (green) is the spatio-kinematic modelling, in which the jet model is fitted to the data, using an MCMC-fitting routine. Third is the radiative transfer modelling (red). The final stage is the estimation of the mass-accretion rates onto the companion (orange).
