        Field name prefix for an instrumental flux that should be aperture
        corrected.
 
    Notes
    -----
    The prefix ``name`` corresponds to the fields ``name_instFlux``,
    ``name_instFluxErr`` and ``name_flag``. For example, specifying
    ``base_PsfFlux`` will select the fields ``base_PsfFlux_instFlux``,
    ``base_PsfFlux_instFluxErr`` and ``base_PsfFlux_flag``.
