Notes. ^(a) Corrected for instrumental broadening & gas velocity dispersion using the ``equivalent rectangular measure'' (Shane & Bieger-Smith 1966).
^(b) Corrected for instrumental broadening & gas velocity dispersion by quadratic subtraction, see Eq. (9).
^(c) Uses the standard Fall & Efstathiou (1980) parametric rotation curve form, constant , and a 2D exponential surface density to model the XV diagram.
^(d) Corrected for broadening & beam-smearing (see Olling's method in Sect. 2.6).
^(e) Asymmetric drift correction applied.
^(f) Using distance measured by van der Kruit (1981) for NGC 891.
 Re-analysis of NGC 891 data observed by Sancisi & Allen (1979).
 New deeper WSRT NGC 891 data - 144 h.
 Re-analysed subset of the Swaters (1999) dataset.
 Includes re-analysed NGC891 data observed by Swaters et al. (1997).
