Notes. The full table is available in electronic form at http://amiga.iaa.es and at the CDS. The columns correspond to (1) the galaxy identification according to the CIG; (2) the projected angular radius, in arcmin, equal to the adopted distance at 1 Mpc; and (3) the ratio between projected angular radius at 1 Mpc (in arcmin) over the original field radius used in the CIG isolation criteria. When the ratio is greater than or equal to 1, the fixed physical radius of 1 Mpc covers the entire original area. (4) Result of the CIG isolation criteria: “1” if the galaxy passes, “0” if it fails. (5) QKar,p, tidal strength estimate of similar-size neighbours. (6) ηk,p, local number density of similar-size neighbours.
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.
