Magnitudes reported for both static (DC) and time-varying (AC) measurements were obtained by vector summation of the fields recorded at the 3 perpendicular axes (x,y,z). The AC measurements reported for each environment correspond to the frequency with maximum amplitude in a spectrum up to 600 Hz. All spectrums had maximums at 60 Hz and were mainly composed harmonics of that frequency. The attenuation values are referenced to the readings made on the laboratory bench. The static magnetic field measurements have an uncertainty of ± 5 × 10^-7 T; time-varying magnetic fields have an uncertainty of ± 6 × 10^-8 T.
