Description:
    This  file contains spectral classifications  for stars collected from
    the literature, serving as a continuation of the compilations produced
    by the Jascheks,   by Kennedy,  and  by Buscombe.  The  source of each
    spectral  type is indicated  by a standard  19-digit bibcode citation.
    These papers of course should  be  cited  in  publication,   not  this
    compilation.
    The stars  are identified either by the  name used in each publication
    or by a valid  SIMBAD  identifier.   Some  effort  has  been  made  to
    determine accurate (∼1" or better) coordinates for equinox J2000,  and
    these  serve as a secondary identifier.  Magnitudes are provided as an
    indication of brightness, but these data are not necessarily accurate,
    as they often derive from photographic photometry or rough estimates.
    The  classifications include MK types as well as types not strictly on
    the MK system (white dwarfs, Wolf-Rayet, etc),  and in addition simple
    HD-style  temperature types.   Luminosity classes  in the  early Mount
    Wilson style (e.g. 'd'  for dwarf,  'g'  for giant)  and other similar
    schemes  have been converted to modern  notation.  Since a citation is
    provided for each  entry,  the  source paper  should be  consulted for
    details  about  classification  schemes,   spectral  dispersion,   and
    instrumentation used.
    The  file includes only  spectral types determined  from spectra (viz.
    line  and band strengths  or ratios),  omitting  those determined from
    photometry (e.g.  DDO,  Vilnius)  or inferred from broadband colors or
    bulk spectral energy distributions.
    System-defining primary  MK standard stars are  included from the last
    lists by Morgan and Keenan, and are flagged by a +  sign in column 79.
    The  early-type   standards  comprise  the   1973  "dagger  standards"
    (1973ARA&A..11...29M 1973ARA&A..11...29M)   and stars from the Morgan,  Abt,  and Tapscott
    atlas (1978rmsa.book.....M 1978rmsa.book.....M).  Keenan made continual adjustments to the
    standards lists up to the time  of  his  death.   Thus  the  late-type
    standards comprise  those marked as high-weight  standards in the 1989
    Perkins  catalogue (1989ApJS...71..245K 1989ApJS...71..245K  = III/150),  plus the carbon-
    and S-type standards (1980ApJS...43..379K 1980ApJS...43..379K,  1996ApJS..105..419B 1996ApJS..105..419B),  and
    class IIIb 'clump giants' (1999ApJ...518..859K 1999ApJ...518..859K).  In addition,  I have
    made  use of the final types by Keenan up to January 2000 shown at the
    Ohio  State Web site (http://www-astronomy.mps.ohio-state.edu/MKCool).
    Though the  present file contains all the  stars in these lists,  only
    those  marked as standards are flagged as such.  Garrison's list of MK
    'anchor   points'   might   also   be   consulted   in   this   regard
    (1994mpyp.conf....3G).
    The  catalogue   includes  for  the  first   time  results  from  many
    large-scale objective-prism spectral surveys done at Case,  Stockholm,
    Crimea,   Abastumani,  and elsewhere.  The stars in these surveys were
    usually identified only on charts or by other indirect means, and have
    been overlooked heretofore because of the difficulty in recovering the
    stars.   More  complete  results  from  these  separate  publications,
    including  notes and identifications,  have been made available to the
    CDS,   and   are   kept   at   the   Lowell   Observatory   ftp   area
    (ftp://ftp.lowell.edu/pub/bas/starcats).   Not all of  these stars are
    present in SIMBAD.
    As a 'living  catalogue',  an  attempt will  be made  to keep  up with
    current  literature,  and to extend the  indexing of citations back in
    time.
