II/224     Catalogue of Stellar Diameters (CADARS)  (Pasinetti-Fracassini+ 2001)

Catalog of Apparent Diameters and Absolute Radii of Stars (CADARS)
(3rd Edition). Comments and statistics

ADC_Keywords: Stars, diameters
Keywords: catalogues - stars: fundamental parameters

Description:
    For 9733 stars this catalog lists all values of the apparent and
    absolute radii from the literature. Data were compiled beginning 1950
    up to 1997.

    The stars are listed according to the following order of
    identification: HD number, DM number, variables with constellation
    name in alphabetical order of the abbreviations, other identifications
    in alphabetical order, LMC and SMC stars. The apparent magnitudes and
    spectral types are those reported by the authors, as they are basic
    data used in some methods for obtaining the stellar diameters.

    The  catalogue is followed by the lists of the Remarks and References.
    Details and statistics will appear in A&A Suppl.

    This version supersedes the previous editions by M.Fracassini, L.E.
    Pasinetti, F. Manzolini (1981A&AS...45..145F, Cat. <II/61>); and M.
    Fracassini, L.E. Pasinetti-Fracassini, L. Pastori and R. Pironi
    (1988BICDS..35..121F, Cat. <II/155>)

--------------------------------------------------------------------------------
Note on Vmag:
    Apparent visual magnitude given by the Authors, otherwise by SIMBAD;
    remarks (W) specify magnitudes in other wavelengths.
    For variable stars: magnitude at maximum luminosity

Note on Diam:
    Apparent diameter (arcsec) of the uniform disk.
    Three significant figures are given; values given with more figures
    are reported in the remarks (file "notes.dat").  Remarks specify other
    cases and/or values corrected for the limb darkening (L): errors (E)
    are given in Remarks for uniformity with the previous versions.

Note on Rad:
    errors in gieven in Remarks.
    Averaged absolute radius are given for Cepheids (code 5, 5A, 5B).

Note on rem:
    In the file "notes.dat", the star identifier is followed by the
    code of the source. The remark codes are:
        B Spectroscopic binary
        D Double star
        G Cluster, group, aggregate or association membership
        R Value of the diameter and/or radius corrected for the
          interstellar reddening. This remark is not used for the
          values from method 6F, all corrected for the reddening.

    Codes calling attention to the file of the Remarks:
        A General characteristics
        E Mean error of the apparent diameter and/or absolute radius
        L Value in the catalogue obtained by a particular law of limb
          darkening; Remarks give other values of the uniform disk and/or
          values corrected for the limb darkening
        W Wavelength (or bandwidth) of measurement of apparent diameter
          and/or absolute radius and/or apparent magnitude when different from
          the visual one.

Methods:

    The methods  of determination  were classified  as direct  or indirect
    methods.  A  more  detailed  subdivision  is  based  on  the  physical
    principles  of determination.  References regarding the first measures
    and/or basic papers are given.
