Notes. Seeing refers to the optical seeing measured with the DIMM facility at the time of observations. DIT: detector integration time, NDIT: number of DITs obtained per frame, EXPTIME: resulting exposure time per position, Nframes: number of images obtained, Nused: number of images with good quality, tdriz: total integration time in the final, drizzled image, FWHM: full width at half maximum of the PSF in milliarcseconds (mas), NGS: brightness of the natural guide star. The Arches 2002 data are described in detail in Stolte et al. (2002).
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.
