This standardized document follows the rules of the Standard Description for Astronomical Catalogues. For those having to work on this catalogue using FORTRAN programs, this ReadMe file can be transformed into a f77-compliant program which reads the files making up this catalogue, in two versions: either a f77 program loading whole files into arrays, or a f77-program reading each data file line by line.
III/233B Catalogue of Stellar Spectral Classifications (Skiff, 2005)
================================================================================
General Catalogue of Stellar Spectral Classifications

ADC_Keywords: Spectral types
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) and stars from the Morgan, Abt, and Tapscott
atlas (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 = III/150), plus the carbon-
and S-type standards (1980ApJS...43..379K, 1996ApJS..105..419B), and
class IIIb 'clump giants' (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.
