2026-03-16 Galactic Large-scale Filaments Resident in Asymmetric Environments: Clues from Cross-filament Profiles of Density and Temperature doi:10.57760/sciencedb.29792 en 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.
