We present a deep and very spatially extended CTIO/DECam g and r photometric catalogue of point-sources (reaching out to ~2 magnitudes below the oldest main-sequence turn-off...
本研究构建了一套兼具高测光深度与极广空间覆盖范围的点源测光星表，该星表采用CTIO/DECam（Cerro Tololo Inter-American Observatory/Dark Energy Camera，智利托洛洛山美洲际天文台/暗能量相机）的g波段与r波段测光数据，其探测极限可达比最古老主序星拐折点暗约2个星等的水平……
