VISIONS DR2 J band HiPS

VISIONS - VISTA Star Formation Atlas is a near-infrared (NIR) VISTA public survey covering all major nearby star-forming regions accessible from the southern hemisphere. The survey is designed to deliver deep high-sensitivity observations of areas with large amounts of extinction, control fields which sample the predominant stellar populations in largely extinction-free regions, and wide field data in multiple epochs on large areas surrounding the targeted star-forming regions. This data release contains all collected observations from April 2017 to October 2021 on the Corona Australis star-forming region for a total of 3360 submitted files. The area covered amounts to about 43 deg2.

VISIONS - VISTA星形成图集（VISIONS - VISTA Star Formation Atlas）是一项覆盖南半球可观测范围内所有主要邻近恒星形成区的近红外（NIR）VISTA公共巡天项目。该巡天旨在实现三类观测目标：对高消光区域的深度高灵敏度观测、对基本无消光区域中主导恒星群体进行采样的控制场观测，以及对目标恒星形成区周边大面积区域的多历元广域数据观测。本次数据发布包含2017年4月至2021年10月期间针对南冕座恒星形成区收集的所有观测数据，共提交3360个文件，覆盖面积约为43平方度。
