Both the EFIS magnetometer as well as the backup magnetic compass.

After sealing this, everything was well within specs (less than 100ft/min altitude loss and less than 10kts/min speed loss). In the end, the speed drop was about 2 knots and the altitude loss 20ft per minute.

We used a calibration kit from the local maintenance provider to check accuracy. Amazingly, the cheap UMA backup instruments proved to be quite accurate.
