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 Pasinetti-Fracassini L.E., Pastori L., Covino S., Pozzi A. <Astron. Astrophys. 367, 521 (2001)> =2001A&A...367..521P
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) File Summary:

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 given 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.
