KiDS survey observing strategy.
| Filter | Exposure time | Exposures | Sequence duration | PSF FWHM | Mag limit | Lower PM limit | Upper PM limit |
|---|---|---|---|---|---|---|---|
| (s) | (s) | (′′) | (AB 5σ 2″) | (′′/h) | (′′/h) | ||
| u | 250 | 4 | 1176 | 1.1 | 23.8–24.4 | 0.05–0.08 | 160 |
| g | 180 | 5 | 1120 | 0.9 | 24.6–25.4 | 0.05–0.08 | 200 |
| r | 360 | 5 | 2020 | 0.8 | 24.6–25.3 | 0.03–0.04 | 100 |
| i | 240 | 5 | 1420 | 1.1 | 22.9–24.4 | 0.04–0.06 | 167 |
Notes. Exposure times in seconds, number of total exposures, the mean sequence duration in seconds, the full-width half-maximum of the point spread function in arcseconds, and the limiting magnitude for the different filters. The last two columns give an estimate of the theoretical lower proper motion limit derived by the sequence duration and residualdispersion, and the upper proper motion limit given by the cross-matching radius. After de Jong et al. (2015).
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.
