Beginning of ReadMe : II/300 JMMC Stellar Diameters Catalogue - JSDC (Lafrasse+, 2010) ================================================================================ An all-sky catalogue of computed star diameters using the SearchCal webservice. Lafrasse S., Mella G., Bonneau D., Duvert G., Delfosse X., Chelli A. <SPIE Conf. on Astronomical Instrumentation 77344E (2010)> =2010SPIE.7734E.140L ================================================================================ ADC_Keywords: Stars, standard ; Interferometry ; Fundamental catalog ; Photometry, infrared ; Parallaxes, trigonometric; Stars, diameters Keywords: catalogs - stars: fundamental parameters - instrumentation: interferometers - techniques: interferometric Abstract: This catalogue contains stellar angular diameter estimate for bright stars, complete for all stars with Hipparcos parallaxes. The JMMC Calibrator Workgroup has long developed methods to estimate the angular diameter of stars, and provides this expertise in the SearchCal software (http://www.jmmc.fr/searchcal). "SearchCal" creates a dynamical catalogue of stars suitable to calibrate Optical Long-Baseline Interferometry (OLBI) observations from on-line queries of CDS catalogues, according to observational parameters. In essence, SearchCal is limited only by the completeness of the stellar catalogues it uses, and in particular is not limited in magnitude. SearchCal being an application centered on OLBI peculiar purposes, it appeared useful to publish the estimated angular diameters of all stars with known parallaxes in a static catalogue. The present catalogue of stellar angular diameters has been obtained from an automated SearchCal results aggregation on the whole celestial sphere. For each star, the value of the limb-darkened angular diameters are computed using a surface brightness method and calibrations for (B-V), (V-R) and (V-K) color indexes. Stars whose angular diameters estimated from the various color indexes are not comparable, are rejected, and a reliable error on the estimated diameter is computed (1). For details of the method see Bonneau et al. (2006A&A...456..789B). To avoid specific confusion problems, spectroscopic binaries in the 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix et al., 2009, Cat. B/sb9) or close visual binaries with a separation of less than 2 arc seconds in the Washington Visual Double Star Catalog (Mason et al., 2001, Cat. B/wds) have been filtered out. Description: Limb Darkened and Uniform Angular diameters are given for 38472 stars, extracted from the All-sky Compiled Catalogue of 2.5 million stars (I/280, Kharchenko et al. 2009). The limb darkened diameters are computed using the V magnitude and the (V-K) color index. The uniform disk diameters are computed for the photometric bands (B, V, R, I, J, H, K) using the linear limb darkened coefficients from (Claret & Diaz-Cordoves, 1995, Cat. J/A+AS/114/247). For each star, HD and Hipparcos catalog numbers, equatorial coordinates, parallax, spectral type, photometric data (B,V,R,J,H,K) and angular diameters are given. Additionnally, the absence of a particular star in this catalogue can also be due to a missing photometry in one of the base catalogues. Conversely, the rejection of binaries depends on their availability as such in the relevant catalogues.
