Cousins RI photometry of NGC 2169

We have used Cousins RI CCD photometry from the Isaac Newton telescope and intermediate-resolution spectroscopy from the Gemini North telescope to identify and characterize...本研究采用艾萨克·牛顿望远镜（Isaac Newton Telescope）获取的考辛斯RI波段CCD测光（Cousins RI CCD photometry）数据，以及北双子座望远镜（Gemini North Telescope）获取的中分辨率光谱数据，以完成……的识别与特性表征工作。
