Notes. Column 1: source name. Column 2: right Ascension. Column 3: declination. Column 4: effective integration time on-source. Column 5: systemic local standard-of-rest radial velocity (radio covention). Column 6: H i line width at 50% of the peak flux density. Column 7: H i integrated flux density. Column 8: 5σ error in integrated flux density. Column 9: note on detection. Detections are ≫5σ, non-detections are ≪5σ, marginal detections are >5σ and uncertain detections are ~5σ. Column 10: profile of the H i line, single (s)- or double (d)-peaked and symmetric (sym) or asymmetric (asym).

(a)

The H i line is dominated by the H i gas in the nearby spiral galaxy UGC 139 (Sect. 2.2.2).

(b)

Baseline problems.
