Notes: The columns show the (1) ID numbers, (2) names, (3) redshifts taken from the catalogues where they are picked from, (4) dates of observation, (5) average seeing, and (6) airmass during observation, (7) used filters for their observations, (8) K band magnitudes taken from Flesch (2021) and Storey-Fisher et al. (2024), (9) total integration time, and (10) S/N based on the peak line flux of Hα line. Ks refers to the K short filter (2.00-2.30 μm) while GRF refers to the red grism (1.53-2.52 μm).
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.
