+----------+--------------------+---------------------------------------------------------------------+-------------+ **Quality flag for redshift catalog** The quality of the redshift estimate must be interpreted differently depending on whether the user is interested in a specific type of object. Indeed, for a user interested in Halpha emitters, the failure of the star classification algorithm may not be a significant quality criterion. Users are therefore advised to : - Check the ``SPE_ERROR_FLAG`` flag value. The value of the ``SPE_ERROR_FLAG`` flag should be equal to ``0`` (see the table dedicated to ``SPE_ERROR_FLAG`` for more details on the meaning of flag values). - For users interested in galaxy solutions, check the ``SPE_GAL_ERROR_FLAG`` flag value. The value of the ``SPE_GAL_ERROR_FLAG`` flag should be equal to ``0`` (see the table dedicated to ``AMAZED_ERROR`` for more details on the meaning of flag values). - For users interested in star solutions, check the value of the ``SPE_STAR_ERROR_FLAG`` flag. The value of the ``SPE_STAR_ERROR_FLAG`` flag should be equal to ``0`` (see the table dedicated to ``AMAZED_ERROR`` for more details on the meaning of flag values). - For users interested in QSO solutions, check the ``SPE_QSO_ERROR_FLAG`` flag value. The value of the ``SPE_QSO_ERROR_FLAG`` flag should be equal to ``0`` (see the table dedicated to ``AMAZED_ERROR`` for more details on the meaning of flag values). ``SPE_ERROR_FLAG`` *table*
