    review text
    Starting with a sequence \(A = (A_n)\) of approximation operators, a new sequence of approximation operators \(\Theta(A)\) is constructed. This method is called the \(\Theta\)-transformation. If \(A\) is the sequence of \((C, 1)\)-means of Chebyshev series, then \(\Theta(A)\) provides a pointwise order of approximation similar to the order of the best polynomial approximation.
