The correlation fields D^(0,0)(r) in \(\frac {q}{2\pi }\) (a), \(1/\sqrt {2} (1,1) \cdot \boldsymbol {D}^{(1,1)}(\boldsymbol {r})\) (b), and D^(0,2)(r) in homogeneous distributions of loops with preferred alignment in horizontal direction as described in the text. Contours are labeled by function value in (a). Length and color of the arrows indicate the magnitude of the vectors, qualitatively, in (b) and (c)
