            <description>SPICE CK file that contains TGO measured attitude as provided by the quaternions on the housekeeping telemetry during the science phase. A filter has been applied to remove spurious quaternions due to erroneous time stamps. Note that this filter works well in most cases but fails in some situations in which there is a predominance of wrong time stamps. Created by the ESA SPICE Service (ESS).</description>
