The pitch-roll motion stabilization system failed a few times due to heavy motion and was reset with a software protocol. It is unclear how long the data were not motion-compensated. These times can be identified by coarser vertical and horizontal resolution since the radar was not pointing true vertical, acting as a low-pass filter. " ;
