资源简介:
The basic parameters, the extracted molecular hydrogen column density (N(H2)) and dust temperature (Td) radial profiles of the 35 Galactic large-scale filaments involved in the paper "Galactic Large-scale Filaments Resident in Asymmetric Environments: Clues from Cross-filament Profiles of Density and Temperature" (DOI: 10.3847/1538-4357/ae3c03)."fil_list.txt": basic physical parameters of the filaments. Meanings of the columns are: (1) Parental catalog; (2) Filament ID in their parental catalog; (3) Galactic longitude; (4) Galactic latitude; (5) Line of sight velocity; (6) Distance; (7) Velocity gradient; (8)-(9) Minimum and maximum temperature; (10) Mass; (11) Averaged N(H2); (12) Linearity; (13) Morphology; (14) Filament width, obtained by Plummer-like fitting of the molecular hydrogen radial profile; (15) Length of the MST filament spine; (16)-(18): segment-length-weighted averaged |1-α|, and their uncertainties; (19)-(20): fasy; (21): Length fraction of IAA segments in the filament spine."G2022_fil", "W2016_fil", "W2015_fil": contain the extracted N(H2) and (Td) radial profiles of each filament.In each folder: (1) "note.txt": filament name, number of segments in its MST spine, length of the segments. (2) "NH2": N(H2) radial profile. "sep" and "sep_sig" for the full radial profile, and its uncertainty extracted from a sufficient long region of each segment based on the Herschel Hi-GAL N(H2) maps; "trim" and "trim_sig" for the trimmed radial profile taken into analyzation in the paper. (3) "Td": similar to "NH2", the Td radial profiles of each segment extracted from the Hi-GAL Td maps. (4) "xaxis_trim.txt": x-axis values of the trimmed radial profile.

本数据集包含论文《处于非对称环境中的银河大尺度纤维状结构:来自密度与温度跨纤维剖面的线索》(DOI: 10.3847/1538-4357/ae3c03)所涉及的35个银河大尺度纤维状结构的基础参数、提取得到的分子氢柱密度(molecular hydrogen column density, N(H₂))径向剖面与尘埃温度(dust temperature, Td)径向剖面。 "fil_list.txt":存储各纤维状结构的基础物理参数,各列含义如下:(1) 母源星表;(2) 对应母源星表中的纤维状结构ID;(3) 银河经度;(4) 银河纬度;(5) 视线速度;(6) 距离;(7) 速度梯度;(8)-(9) 最低与最高温度;(10) 质量;(11) 平均N(H₂);(12) 线性度;(13) 形态;(14) 纤维宽度:通过对分子氢径向剖面进行类普朗姆(Plummer-like)拟合得到;(15) 最小生成树(Minimum Spanning Tree, MST)纤维脊线长度;(16)-(18) 经段长加权的平均|1-α|值及其不确定度;(19)-(20) fasy参数;(21) 纤维脊线中IAA段的长度占比。 "G2022_fil"、"W2016_fil"、"W2015_fil":分别存储各纤维状结构提取得到的N(H₂)与Td径向剖面。每个子文件夹内包含以下内容: (1) "note.txt":记录纤维名称、其MST脊线的分段数量与各分段的长度; (2) "NH2":N(H₂)径向剖面数据。其中,"sep"与"sep_sig"对应完整径向剖面及其不确定度,该数据基于赫歇尔(Herschel)Hi-GAL的N(H₂)地图,从每个分段的足够长区域中提取得到;"trim"与"trim_sig"对应本文分析中采用的修剪后径向剖面; (3) "Td":与"NH2"类似,存储从Hi-GAL Td地图中提取的各分段的尘埃温度径向剖面; (4) "xaxis_trim.txt":修剪后径向剖面的横轴数值。
