UBVRI photometry of 3 young open clusters

In this paper we present and analyze CCD UBVRI photometry in the region of the three young open clusters NGC 3114, Collinder 228, and vdB-Hagen 99, located in the Carina spiral...本文对位于船底座旋臂内的三个年轻疏散星团——NGC 3114、Collinder 228以及vdB-Hagen 99——所在天区的电荷耦合器件（Charge-Coupled Device，CCD）UBVRI测光数据进行了介绍与分析。
