Distributions and correlations of key filament parameters for core-scale subcritical (squares) and supercritical (stars) filaments. Intrinsic total linear mass density M_line,tot, core linear mass density M_line,core, wing linear mass density M_line,wing, and ratio M_line,core/M_line,wing. Low-background filaments (LBs: blue/green) are separated from those in denser (high-background) environments with A_V> 2.2 mag (HBs: magenta/red) (see text). For each type of environment, filaments are further separated according to the relative contribution of core/wing components to their M_line,tot: core-dominated (blue/magenta for LBs and HBs, respectively), and wing-dominated (green/red).The 1:1 relation (blue solid line) is shown for reference.
