Table A.5.

HI results from our campaign and the literature. The complete table is available in electronic form at the CDS. Column description: (1-2) galaxy ID and distance, for the sources denoted with the symbol ^a we report redshift-independent distances; (3) velocity integrated HI flux, sources denoted with the symbol ^b correspond to tentative HI detections with S/N< 3 from our campaign at Nançay; (4) HI line width (W50), reported only for detections from our campaign; (5) HI mass; (6) reference. Upper limits are at 3σ. Here, — marks absent values. The last 11 sources were observed as part of our campaign at Nançay, but subsequently excluded from our sample of filament galaxies. See text for further details.
