Conventions Used in the MTPy Software

  1. MTpy uses E- and B-fields (although the sensors may be confusingly named as H-sensors in EDI files)
  2. [E] = microvolts/meter (muV/m)
  3. [B] = nanotesla (nT)
  4. [Z] = [E]/[B] = km/s
  5. Apparent resistivty rho = 0.2 * T * |Z|^2 (in Ohm m)
  6. Angles are given in degrees (mod 360)
  7. EDI files can contain data in Z- or rho/phi-form
  8. EDI files contain data from one station only
  9. Coordinates are handled in decimal degrees (converted when reading)
  10. Time stamps refer to UTC
  11. Internal coordinates: X = North-South, Y = East-West
  12. Rotations are interpreted clockwise (mathematically negative)
  13. 0 degrees azimuth = North
