Detailed Description of B/mk :
Catalogue of Stellar Spectral Classifications (Skiff, 2009-2016)

Note : this is the description file of the original catalog.
This HTML page corresponds well to the original description, but some minor
changes in the format may have been introduced in the FITS output
files in order to allow for arithmetic operations on quantities
such as coordinates and times. h:m:s and d:m:s units are normally
converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the
units; the value given in the HTML files supersedes the value indicated in the ReadMe
file for this catalogue.

ADC_Keywords: Spectral types ; MK spectral classification
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
epoch 2000 if possible), and these serve as a secondary identifier. To
the extent possible with current astrometric sources, the components
of double stars and stars with composite spectra are shown as separate
entries.
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 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
spectral energy distributions.
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.
System-defining primary MK standard stars are included from the last
lists by Morgan and Keenan, and are flagged by a + sign in column 83.
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). Standards from Table I of the Morgan &
Abt 'MKA' paper (1972AJ.....77...35M) not appearing in the two later
lists are added. 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); the revised S-type
standards in collaboration with Boeshaar (1980ApJS...43..379K); plus
the carbon standards and class IIIb 'clump giants' in collaboration
with Barnbaum (1996ApJS..105..419B and 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.ohio-state.edu/MKCool), accessed in autumn 2003.
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, and
http://www.astro.utoronto.ca/~garrison/mkstds.html).
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.
