@tobie >It would also be nice to understand and document the way external hard iron distorsion is normally compensated for (I imagine there's some sort of filtering going on?). To get from uncalibrated to calibrated values, the implementation must apply a transformation matrix to uncalibrated values at point (x, y, z). This process happens in hardware usually. To build the transformation matrix, the implementation asks you to manually do the [calibration][1]. @alexshalamov @kenchris to correct me if I'm wrong here.
