Notes. Column (1) Target name; Col. (2) Observation date; Col. (3) Observation mode, ON for on-axis mode with light spitted in half into the science and FT and OFF for off-axis mode with all of the light used by the FT; Cols. (4)–(6) Averaged seeing, coherence time, and Strehl ratio during the observation; Col. (7) Nuclear K-band magnitude of the target measured by the GRAVITY FT. The typical uncertainty is 0.2 mag based on our multiple exposures during the same night; Col. (8) Total V-band magnitude from SIMBAD.
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.
