Table 9 Proportion of measurements of alignment sampled during 2 hrs-periods (and during the night) and proportion of measurements (from the total) sampled in respective periods under conditions of quiet magnetic field (i.e., with no changes in declination)

From: Dogs are sensitive to small variations of the Earth’s magnetic field
