In order to estimate the multiples we need to eliminate the primaries
as much as possible, even if that implies underestimating the multiples.
On the other hand, since the estimate of the primaries is only used as
a weight function for the adaptive matching of the multiples, in
estimating the primaries we would prefer to overestimate the multiples.
The choice of the mute pattern is obviously important and requires
careful examination of the SODCIGs.
