| Area id | Area | Exp time | σmedpix | 5σ limit |
|---|---|---|---|---|
| □′ | (h) | (nJy/pix) | (AB mag/nJy) | |
| A | 1.12 | ≳37 | 0.20 | 28.65/12.6 |
| B | 1.64 | ≳24 | 0.24 | 28.48/14.7 |
| C | 0.80 | ≳7 | 0.50 | 27.68/30.8 |
| A+B | 2.76 | ≳24 | 0.22 | 28.58/13.4 |
| External | 1.15 | ∼1–6 | ∼0.9 | ∼27/∼50 |
Notes. Areas are indicated in Fig. 4. σmedpix calculated within apertures with diameter ⌀ = 0.45″, corrected for the drizzling correlation (a multiplicative factor 2.24, see text for details). The limiting magnitude is for a point source and includes the pixel correlation correction and aperture correction.
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.
