            <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 his filter works well in most cases but fails in some situations in which there is a predominance of wrong time stamps.</description>
