Rather than being simply apsidal in form, the northern range of the drum tower was apsidal towards its southern end and was squared off towards its northern side, which may indicate the presence of a garderobe. The dense point cloud generated over 15 million points with a mean RMS error of 0.006m. The Ground Sampling Distance (GSD) achieved was a great 0.301cm/pixel.
