While the anomalous regions in C and N have slightly different shapes, the differences are at the limit of the lateral resolution of these smoothed images and are, therefore, of limited importance. However, all extracted C and N isotopic ratios (e.g., Fig. 1) refer to identical. regions of interest and are, thus, spatially correlated.
