RibEye - physical dimension DC for the absolute position

[Sebastian Rings]

Currently the RibEye channel codes listed on page 6/6 of "OTHER Chest Deflection Measurements" use the physical dimension DS (e.g. "??TRRILUFRWSDSY?"). Often the channels are offset corrected, i.e. starting at 0mm at time zero. Then DS is ok. But shouldn't we use DC if the channels contain the absolute position (distance to a specific reference point in X, Y and Z direction)? This absolute position is required when deriving signals equivalent to the IR-TRACC/S-Track.
