JSDC : The JMMC Stellar Diameters Catalog

Introduction

We compiled a new static catalogue of 38472 bright star diameters, known as JSDC (JMMC Stellar Diameters Catalog). All those selected stars have a parallax measurement and we use the "Bright" option of SearchCal presented in Bonneau et al. (2006) to compute their diameters. The catalogue conforms to the following scientific criteria :

• The whole sky should be covered;
• The largest possible magnitude range in K band should be harvested (from a theoretical -5.0 up to 20.0, applied to the bright scenario);
• No inclusion of previously computed diameters extracted from foreign catalogs (to have a consistent computation method for each catalog’s diameters);
• Tight result filtering, to eliminate obvious false positive like multiple stars of same color and so on;
• Restricted column set, to clearly present diameters and star properties used to compute them;

Documentation

An SPIE2010 paper and poster presented at San Diego further describe JSDC.

The JSDC catalogue access is given onto Vizier (Cat. II/300) thanks to the CDS services.
