| 2015/05/15 | 0.45–0.57 | 7–10 | 1.04–1.03 | IRDIFS_EXT | YJH + K1K2 | 64 × 64 | 63.6 | 0.78–0.85 |
Notes. The columns provide the observing date, the seeing and coherence time measured by the differential image motion monitor (DIMM) at 0.5 μm, the airmass at the beginning and the end of the sequence, the observing mode, the spectral bands, the DIT (detector integration time) multiplied by the number of frames in the sequence, the field of view rotation, and the Strehl ratio measured by the AO system.
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.
