JSDC星表 Version 2

This catalogue contains stellar angular diameter estimates for nearly all the stars of the Hipparcos and Tycho catalogue that have an associated spectral type in Simbad/CDS. The median error on the diameters is around 1.5%, with possible biases of around ∼2%.本星表收录了依巴谷（Hipparcos）与第谷（Tycho）星表中几乎所有在SIMBAD/CDS中带有关联光谱型的恒星的角直径估算值。该批角直径估算值的中位误差约为1.5%，可能存在约2%的系统偏差。
