Notes. ^(a)Number of individual images used to create a tile: N = number of pawprints (6) × NJITTER. ^(b)Computed by multiplying the pixel scale with the mean FWHM determined via IRAF/imexam. ^(c)Three exposures could not be used due to bad quality and high readout noise of some detectors.

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.
