Notes. The central wavelengths (CWs) of the CRISP prefilters are nominally one or a few tenths of a nm to the red of the wavelengths listed here, but tilted by small angles to center the passbands on the core wavelengths of the spectral lines for which they are usually used. θz denotes the zenith angle of the telescope pointing. The 11:49 scans are referred to below as the “extra” DA scans.

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.
