World magnetic model frame of reference??

I am using the world magnetic model function wrldmagm as part of a scrip, but the help page that describes the function provides no information about the reference frame used for the magnetic vector. The simulink block seems to use North-East-Down, would it be safe to assume that the script function does the same?

The XYZ — Magnetic field vector stand for North-East-Down whcih can be confimed from the Visualize World Magnetic Model Contours for 2020 Epoch example where it is mentioned that, they have used the 'wrldmagm' function where
  • X - North component of magnetic field vector in nanotesla (nT)
  • Y - East component of magnetic field vector in nanotesla (nT)
  • Z - Down component of magnetic field vector in nanotesla (nT)
I hope it clears your query.
