1Surveys refer to fig. 1.
2Flight-altitude: AG, survey originally flown "above ground" in draped mode at a constant elevation above terrain; B, survey originally flown at constant "barometric" elevation.
3Data type: A, data exist in "analog" form only--subsequently, maps were digitized from published versions; D, data exist as original "digital" flight-line data.
4Reference cited: References refer to published versions of the individual aeromagnetic surveys used in the compilation.
