   I have extracted from GCVS 4 to confirm Ishida-san's suspicion.

   Of all stars classified as SRC (or SRC:), 10 have no spectroscopic
information of the luminosity class.  The number would be smaller enough
than that of potential SRc stars presently only classified as SR (of course
depending on the definition of the SRc class -- as Ishida-san pointed out).

   Are there more 'hidden' SRc stars among naked-eye stars?

   What about SRc stars in the LMC, as may have been inferred from the
recent MACHO surveys?
