Information on magnetic data processing is given in the original publication by Oshetski and Kucks, 2000.  We reduced these observed magnetic data to the pole, a technique that attempts to account for the inclination of the Earth's magnetic field. Its principal effect is to shift magnetic anomalies to positions directly above their sources.  We used a declination of 11 degrees and inclination of 66 degrees for the entire state in the reduction-to-pole calculation.
