%description
We implemented a Bayesian-statistics approach for subtraction of
incoherent scattering from neutron total-scattering data. In this
approach, the estimated background signal associated with incoherent
scattering maximizes the posterior probability, which combines the
likelihood of this signal in reciprocal and real spaces with the prior
that favors smooth lines. The description of the corresponding approach
could be found at Gagin and Levin (2014) <DOI:10.1107/S1600576714023796>.
