Notes. The sources of the data are noted for each parameter. The seeing is measured by the Differential Image Motion Monitor (DIMM) at 0.5 μm. Coherence time after 2016-04-05 has additional measurements from the Multi-Aperture Scintillation Sensor (MASS). The DIT (detector integration time) refers to a single exposure time. (a)Astronomical site monitor (ASM) DIMM seeing sampled every 79s. (b)MASS-DIMM combined measurements sampled every 79s. (c)Measurements before 2016-04-05 accessed from historical ambient data; sampled every 60s with DIMM3. (d)Vaisala meteorological station measurements sampled every 60s. (e)European Centre for Medium-Range Weather Forecasts (ECMWF) Climate Data Store (CDS). ECMWF re-analysis (ERA5) sampled every hour.

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.
