C, control site outside of the anomaly; B, site at the border of the anomaly; A, site within the anomaly. αhome, dhome,direction and distance to the loft, respectively. ΔB to home, difference in magnetic intensity to the home site; ΔB, the maximum difference in intensity in nT within 1 and 2.5 km, with * indicating that the maximum difference is closer than 1 or 2.5 km, respectively; Dir., the direction in which the maximum difference is found. Max. differences within 1 and 2.5 km, the maximum difference of intensities within a radius of 1 and 2.5 km around the release point, respectively; the last 2 columns indicate the differences in home direction
