BV photometry of NGC 1866

We present a new deep (down to V~24) photometry of a wide region (~6'x6') around the Large Magellanic Cloud globular cluster NGC 1866. Our sample is much larger (by more than a...本研究针对大麦哲伦星系（Large Magellanic Cloud）的球状星团（globular cluster）NGC 1866周边约6′×6′的广域天区，提供了一套深度可达V波段24等的新型测光（photometry）数据。本次研究的样本规模远超此前相关研究（超出一倍以上……）
