We prove the following corrections theorem: Any function f on the circle \( {\mathbb T} \) that is bounded by an α 1-weight w (which means that \( M{w^2} \leqslant C{w^2} \)) can be modified on a set with \( \mathop \smallint \limits_e w \leqslant \varepsilon \) so that its quadratic function built up from an arbitrary sequence of nonintersecting intervals in ℤ will not exceed \( C\log \frac{1}{\varepsilon }w \).
