World magnetic model components coordinate system

[Lelelo1]

Hello and thanks for this api

I am wondering about the world magnetic model components X, Y, Z. What is the coordinate system they are given in? I think I need to convert them ENU since it it is the standard in Android and iOS sensors that I am working with.

I think they are given in NED, looking at these docs: https://ahrs.readthedocs.io/en/stable/wmm.html

I also found mavlink/mavros#49 how to swap the axises. I would preferably want to have a quaternion for it though
