Frame chain and coordinate systems

The figure below shows the frame chain for the current complete frame. The frame chain is stored between the

BCS and WCS. The SZS (Settable Zero System) corresponds to the WCS, transformed by the programmable

frame. The BZS (Basic Zero System) still includes the current settable frame. The system frame for the zero

offset external is only available if it has been configured, otherwise the zero offset external is interpolated as a
