We present the fourth installment of the Yale/San Juan Southern Proper Motion Catalog, SPM4. The SPM4 contains absolute proper motions, celestial coordinates, and (B,V) photometry for over 103 million stars and galaxies between the south celestial pole and -20 deg declination. The catalog is roughly complete to V=17.5 and is based on photographic and CCD observations taken with the Yale Southern Observatory's double-astrograph at Cesco Observatory in El Leoncito, Argentina. The proper-motion precision, for well-measured stars, is estimated to be 2 to 3 mas/yr, depending on the type of second-epoch material. At the bright end, proper motions are on the International Celestial Reference System by way of Hipparcos Catalog stars, while the faint end is anchored to the inertial system using external galaxies. Systematic uncertainties in the absolute proper motions are on the order of 1 mas/yr.

The Southern HII Region Discovery Survey. II. The Full Catalog
南半球HII区域发现巡天（英语：Southern HII Region Discovery Survey，缩写：SHRDS）是澳大利亚望远镜紧凑阵列（英语：Australia Telescope Compact Array）对南半球银河系HII区域和红外线识别的HII候选区域进行的900小时4-10 GHz射电连续谱和射电复合线巡天。对于本次数据发布，我们重新处理了所有先前发布的SHRDS数据，并包括额外的约450小时的观测。对新的HII区域的搜索现已完成，范围为259度<银河经度< 346度，|银河纬度|30 < 4 deg for HII region candidates with predicted 6 GHz continuum peak brightnesses >mJy/梁。我们检测到无线电连续发射对730个目标，包括以前已知的星云和HII区域的候选人。通过平均约18 RRL转换，我们检测到RRL发射到206以前已知的HII区域和436 HII区域候选者。在过去的十年中，包括北部天空调查在内，HII区域发现调查使已知的银河系HII区域数量增加了一倍以上。银河系HII区WISE星表中HII区的普查现在已经完成，其星云的9 GHz连续通量密度大于250 mJy。我们比较了新发现的SHRDS星云的RRL属性与所有以前已知的HII区域。整个WISE星表HII区域的…
Milky Way Tomography with the SkyMapper Southern Survey. II. Photometric Re-calibration of SMSS DR2
我们应用基于光谱的恒星颜色回归（SCR）方法对SkyMapper南方巡天（SMSS DR 2）的第二次数据发布进行精确的光度重新校准。通过与20多万颗矮星的样本进行比较，这些矮星的恒星大气参数取自GALAH+ DR 3，而$Gaia$ DR 2的光度测量则精确、均匀，在SMSS DR 2的原始光度星表中发现了零点偏移，特别是对重力和金属敏感的$Gaia$波段。对于$uv$带，零点偏移在非常低的消光下接近于零，然后随着$E (B - V)$稳定增加，在$E (B - V) \sim 0.5$磁级分别达到0.174和0.134磁级。这些偏移主要来自SMSS DR 2用于从ATLAS参考星表构建光度校准器的转换中采用的尘埃项。对于$gr$带，零点偏移表现出可忽略的变化与SFD $E(B - V )$，由于其微小的系数上的灰尘项的转换。我们的研究还揭示了所有$uvgr$波段中零点偏移的小但显著的空间变化。外部检查使用斯特伦格伦测光，WD轨迹和SDSS条纹82标准星表独立确认零点发现我们的修订SCR方法。
