Where FiffDigPointSet is a flat point list, FiffDigitizerData is the registration-ready view: the dig points themselves, the device→head FiffCoordTrans recovered from HPI fits, the per-coil goodness of fit, and any comments that travelled with the block. It is the structure the coregistration tooling persists into -dig.fif / -fiducials.fif files and the structure that the forward / inverse pipeline consumes when registering a subject's MRI to the MEG sensor frame.
