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.
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

<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)

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.

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.
