Notes. Systemic velocity (Col. 5) and HI line width at 20% level (Col. 6) are from Fisher & Tully (1981). The distances to NGC 1042 and NGC 4178 are from Tully (1988), that to NGC 4395 from Thim et al. (2004). References for AGN properties and SMBH masses in Cols. (7) and (8) are as follows: NGC 1042: Shields et al. (2008), NGC 4178: Satyapal et al. (2009), NGC 4395: Peterson et al. (2005).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
