Hi Victoria, The default for this parameter is the very curve you are building. You’d set the parameter’s value explicitly in order to replicate a methodology used (the example may not too relevant for too long) to build USD LIBOR curve, where the discounting is done at SOFR (and, before that, at EFF OIS).
