JSDC : The JMMC Stellar Diameters Catalog


We compiled in 2010 our first static catalogue of 38742 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 :


A paper and poster presented at SPIE2010 San Diego further describe the first public release of the JSDC.

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

Preliminary JSDC v2 releases

The JSDC version 2 is currently in progress and a paper and poster presented at ADASS XXIII describe the new JSDC scenario based on SearchCal improvements, study catalog results (more than 55 000 stars, more giant stars) and compare this new release with the former JSDC v1. Some improvements have been performed in the diameter computation. Last progresses have been presented in a POSTER during SPIE in Montreal.
