From: Observations about utilitarian coherence in the avian compass
Compass sensitivity, as captured by the anisotropy \(\Delta _{S}\), is plotted against electronic coherence measures \(\mu [\bar{{\mathcal {C}}}_{i}]\) (a, c, e) and \(\Delta [\bar{{\mathcal {C}}}_{i}]\) (b, d, f), for 878,400 relative orientations of flavin–tyrosine radical pairs. Here, we use equivalent measures to Fig. 2, where additional details are provided; alternative measures are detailed in the SI. Data has been coloured according to the relative orientation angle \(\beta\), ranging from \(0^{\circ }\) (blue) to \(180^{\circ }\) (yellow). Both up-down (UD) and singlet-triplet (ST) bases are considered, and a linear fit (red line) with associated Pearson correlation coefficient R is displayed.
