Notes. A flux uncertainty of 5% is adopted (see text). Column (6) and (8) lists the measured filament lengths and line masses, while column (7) and (9) includes corrections for projection effects (assuming 45^°). Column (10) and (11) lists critical line masses accounting for the purely thermal contribution and a combination of thermal and turbulent motions. Uncertainties for columns (5) and (8)–(11) were calculated using the Monte Carlo method. Uncertainties for columns (6) and (7) were determined through error propagation method.
