Galactic charged cosmic rays (notably electrons, positrons, antiprotons andlight antinuclei) are powerful probes of dark matter annihilation or decay, inparticular for candidates heavier than a few MeV or tiny evaporating primordialblack holes. Recent measurements by PAMELA, AMS-02, or VOYAGER on positrons andantiprotons already translate into constraints on several models over a largemass range. However, these constraints depend on Galactic transport models, inparticular the diffusive halo size, subject to theoretical and statisticaluncertainties. We update the so-called MIN-MED-MAX benchmark transportparameters that yield generic minimal, median and maximal dark-matter inducedfluxes; this reduces the uncertainties on fluxes by a factor of about 2 forpositrons and 6 for antiprotons, with respect to their former version. We alsoprovide handy fitting formulae for the associated predicted secondaryantiproton and positron background fluxes. Finally, for more refined analyses,we provide the full details of the model parameters and covariance matrices ofuncertainties.
