In Stim DEMs, error(p) gives the probability of an error mechanism. In literature where decoding is modeled using syndrome graphs, p is assigned to edges representing detection events. Are these p’s directly the same, or does the DEM p correspond to a more microscopic quantity that needs to be combined to match the syndrome-graph definition?
