Notes. The masses were calculated for each part of the filament as well as the whole filament marked by the red polygons in Fig. 11. The second column gives the molecular hydrogen mass as traced by 13CO emission. The third column shows the total atomic hydrogen mass inferred from the optical depth and continuum corrected H I emission. The fourth and fifth column present the mass of the cold atomic hydrogen traced by HISA with an assumed spin temperature of 20 and 40 K, respectively.The last three columns give the corresponding mass fractions with respect to the H2 mass. (a) This mass was calculated using the corrected H Iemission between 43 and 56 km s−1, 20.6 > ℓ > 17.6° and − 1.25 < b < +0.5°.
