Notes. In the ESO observations, the slit was centered and guided at the CSPN. In the SAAO observations, the slit was moved to various positions in the target, indicated by the numbers. The coordinates were calibrated later using 2MASS stars. The airmass in the two observations is given at the mean time of the observation.
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.
