% Syntax
%
%  [yl, yu] = invse_snn(y_av, err)
%
% Description
%
%  INVSE_SNN takes
%   y_av     - error is around y_av
%   err      - squared error
%  and returns
%   yl       - lowest y for which se_snn(y, y_av) = err
%   yu       - highest y for which se_snn(y, y_av) = err
%

tmp = sqrt(2*e_max);
yu = y_av + tmp;
yl = y_av - tmp;
