摘要：
In [3] we found estimates for the weighted Lebesgue functions, Δn(x), for a class of exponential weights that includes non-even weights, when the interpolation points are the zeros of orthogonal polynomials. In this paper, we use Szabados" method of adding two extra interpolation points to find better estimates for Lebesgue functions.
