Summary: We construct a quadrature formula with $n+1$ angles and positive weights which is exact in the $(2n+1)$-dimensional space of trigonometric polynomials of degree $\leq n$ on intervals with length smaller than $2\pi$. We apply the formula to the construction of product Gaussian quadrature rules on circular sectors, zones, segments, and lenses.
Classification : 65D32
