Properties of the CFHT-MegaCam dataset.
| Filter | u | g | r | i | z | Hα |
|---|---|---|---|---|---|---|
| Integration time per exposure (s) | 240 | 120 | 120 | 240 | 240 | 360 |
| Total number of exposures | 7 | 14 | 51 | 10 | 6 | 7 |
| Mean image quality [arcsec] | 1.46 | 1.23 | 0.79 | 0.56 | 0.60 | 0.49 |
| Sky background level (mag arcsec−2) | 23.07 | 22.3 | 21.3 | 20.5 | 19.2 | 21.2 |
| Compact source depth 10 σ (Kron magnitude) | 24.3 | 25.1 | 25.1 | 24.0 | 22.3 | 22.9 |
| Radially integrated galaxy profiles (mag arcsec−2) | 29.5 | 29.9 | 29.8 | 29.5 | 28.0 | n/a |
Notes. The limiting surface brightness metric is the maximum depth reached for radially integrated profiles on Perseus cluster galaxies using AutoProf. Both compact source performance (Kron magnitude) and diffuse emission performance (LSB) match well with the Euclid NIR observations, facilitating the production of a rich multi-band catalogue.
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.
