Thanks to its high photometric accuracy, a large number of the transits detected by PLATO will be shallow. In this regime, a large fraction of these candidates will consist of blended eclipsing binary systems which can mimic not only a transit signal produced by a planet, but also its radial velocity signature. We present a method to set upper limits to the masses of the components of blended systems based on simulations of the effects produced on radial velocity measurements and diagnostics.
