Notes. M 81-group members with their name, co-ordinates on the sky (J2000), velocity with respect to the heliocentric frame, vhel, and its uncertainty, Δvhel, magnitude in the B-band, their ‘major disturber’ (MD) and tidal index to their MD, Θ1, the distance to us as observers, r, and the method to determine the distance. The last column indicates if the galaxy was used for the Hubble flow fit (HFF) in Sect. 5.3. Rows are sorted according to their distance to M 81. Galaxies in the dataset by Müller et al. (2024) have a * after their name.
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.
Initial download of the metrics may take a while.
