Table A.4.

CO results of our IRAM-30 m campaign. The complete table is available in electronic form at the CDS. Column description: (1-3) galaxy ID, distance, and D₂₅ diameter, for the sources denoted with the symbol ^a we report redshift-independent distances; (4) CO(J→J-1) transition; (5) observed velocity integrated flux, not aperture corrected; (6) filling factor; (7) FWHM of the CO(J→J-1) line; (8) velocity integrated CO(J→J-1) luminosity, tentative detections with S/N< 3 are denoted with the symbol ^b; (9) excitation ratio; (10) total H₂ gas mass. The reported upper limits are at 3σ and calculated at a resolution of 300 km s⁻¹. Here, — marks absent values. The last seven sources were observed as part of our IRAM-30 m campaign, but were subsequently excluded from our sample of filament galaxies. See text for further details.
