MAgnetic data are presented as:
	Total magnetic field (Rana_TotalMAG)
	Magnetic Vertical Gradient (Rana_VG)
	Magnetic Tilt Derivative (Rana_TD)
	Geosoft XYZ-file.

Radiometric data are presented as:
	Total Counts (RAna_Total_Count)
	Potassium ground concentration in % (Rana_Potassium)
	Uranium ground concentaration in ppm (Rana_Uranium)
	Thorium ground concentration in ppm (Rana_Thorium)
	Ternary map (Rana_Ternary)
	Geosoft XYZ-file (Rana_Rad.YYZ)

ElectroMagnetic data are presented as Calculated Apparent Resistivity 
from half space model, In phase and Quadrature Components:
	880 Hz Coplanar (RAna_Res880)
	980 Hz Coaxial  (Rana_Res980)
