Cosmic-ray measurements inform on Galactic cosmic-ray origin and propagation in the Galaxy.
Based on AMS-02 and Voyager coesmic-ray measurements, we have revised various scenarios
of cosmic-ray propagation models under standard assumptions: pure diffusion, diffusion with
convection, diffusion with reacceleration, and diffusion with reacceleration and convection. Aim-
ing at containing as much as possible the number of model parameters such as spectral indexes
and breaks of the main species, we explore the performance of different scenarios. Commonly
accepted long-standing truths are tested and some are put into question.
