    "abstract": "We calculate dilepton production for the reactions $\\pi^-$C and $\\pi^-$Pb at\n1.3 GeV within a semi-classical BUU transport model and compare our results to\na previously published calculation. We show that a modified treatment of the\n$\\rho$-meson production and propagation gives substantially different results.\nWe, furthermore, discuss uncertainties related to the electromagnetic decay of\nthe $\\rho$-meson and the elementary $\\pi^- N \\to e^+ e^- X$ channels.",
