Properties of the Euclid dataset.
| Filter | IE | YE | JE | HE |
|---|---|---|---|---|
| Integration time per exposure [s] | 566.0 | 87.2 | 87.2 | 87.2 |
| Total number of exposures | 16 | 16 | 16 | 16 |
| Mean image quality (arcsec) | 0.16 | 0.48 | 0.49 | 0.50 |
| Sky background level (mag arcsec−2) | 22.3 | 22.1 | 22.3 | 22.5 |
| Point source depth 5 σ PSF magnitude | 28.0 | 25.2 | 25.4 | 25.3 |
| Compact source depth 10 σ (Kron magnitude) | 26.1 | 23.8 | 24.0 | 24.1 |
| Radially integrated galaxy profiles (mag arcsec−2) | 30.1 | 29.1 | 29.2 | 29.2 |
Notes. The limiting surface brightness metric is the maximum depth reached for radially integrated profiles on Perseus cluster galaxies. The sixteen exposures originate from the execution of four Euclid ROSs of four exposures each per filter. A point source stands for stars while a compact source stands for distant galaxies up to a few arcseconds in size at most.
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.
