- MTpy uses E- and B-fields (although the sensors may be confusingly named as H-sensors in EDI files)
- [E] = microvolts/meter (muV/m)
- [B] = nanotesla (nT)
- [Z] = [E]/[B] = km/s
- Apparent resistivty rho = 0.2 * T * |Z|^2 (in Ohm m)
- Angles are given in degrees (mod 360)
- EDI files can contain data in Z- or rho/phi-form
- EDI files contain data from one station only
- Coordinates are handled in decimal degrees (converted when reading)
- Time stamps refer to UTC
- Internal coordinates: X = North, Y = East
- Rotations are interpreted clockwise (mathematically negative)
- 0 degrees azimuth = North
