<GRID FILES>
dtm     = Digital Elevation Model (m, AHD)
mag     = Total Magnetic Intensity (nT)
tot     = Total count (cps)
pot     = Potassium (cps)
ura     = Uranium (cps)
tho     = Thorium (cps)

NOTES:
DTM: DTM = GPShgt - (ralt + sen_sep + nValue)
           GPShgt = GPS height above ellipsoid, parallax corrected
           ralt   = aircraft height above ground, parallax corrected
           sen_sep = GPS/radar altimeter sensor separation
           nValue  = ellipsoid/geoid separation from GEOID94
     DTM has been tie line and micro-levelled and mean adjusted to
     the AUSLIG AHD1984 model
     Gridded using the cubic spline method.
MAG: Corrected for diurnal, IGRF & parallax.
     Tie line levelled and micro-levelled.
     Gridded using the cubic spline method.
RAD: Corrected for parallax, background radiation, Compton scattering,
     Radon and height variation (adjusted to 50 m AGL). Micro-levelling
     applied.
     Gridded using the minimum curvature method.
