3D Cloud Density Cutouts

We provide 3D cutouts of the gas density of each cloud, derived from the Leike, Glatzle, and Enßlin 2020 3D dust distribution. The density corresponds to the total volume density of hydrogen nuclei, in units of cm-3. The WCS information is provided in a Heliocentric Galactic Cartesian reference frame. The spatial scale of the maps is 1 pc. If you use these data, please cite the original 3D dust paper (Leike, Glatzle, and Enßlin 2020, doi: 10.1051/0004-6361/202038169).本数据集提供各星云气体密度的三维截块数据，其推导自Leike、Glatzle与Enßlin于2020年发布的三维尘埃分布成果。该密度值对应氢核的总体积数密度，单位为cm⁻³。世界坐标系（World Coordinate System, WCS）信息采用日心银河笛卡尔参考坐标系给出。本数据集所包含图像的空间尺度为1秒差距（pc）。若您使用本数据集，请引用原始三维尘埃相关论文（Leike、Glatzle与Enßlin，2020，DOI: 10.1051/0004-6361/202038169）。
