BV photometry for components of HIP doubles

Using observations obtained with the Tycho instrument of the ESA Hipparcos satellite, a two-colour photometry is produced for components of more than 7000 Hipparcos double and...本研究基于欧洲空间局（ESA）依巴谷卫星（Hipparcos satellite）第谷仪器（Tycho instrument）获取的观测数据，为7000余个依巴谷双星及……的组成天体生成了双色测光（two-colour photometry）数据集。
