6.4.6 STAMTA

The single-transit analysis (STA) and multi-transit analysis (MTA) modules are integrated in the same workflow, named STAMTA in Figure 6.2. First, STA processes the data per transit to obtain the single-transit spectroscopic radial velocities. Then, MTA combines the single-transit radial velocities to produce the radial velocity of the star, $V_{\rm rad}$, published in Gaia DR2.
