Predicted S/N for the ISW signal in the current realistic scenario, including the dust residuals in the CIB maps.
| Freq. (GHz) | 217 | 353 | 545 | 857 | 3000 |
|---|---|---|---|---|---|
| 10% fsky | 0.88 | 0.91 | 0.83 | 0.65 | 0.28 |
| 20% fsky | 1.46 | 1.51 | 1.41 | 1.14 | 0.52 |
| 40% fsky | 1.16 | 1.16 | 0.99 | 0.69 | 0.27 |
| 60% fsky | 0.92 | 0.90 | 0.74 | 0.49 | 0.18 |
| 70% fsky | 0.80 | 0.78 | 0.63 | 0.42 | 0.16 |
| 80% fsky | 0.59 | 0.57 | 0.45 | 0.30 | 0.11 |
Notes. They are given for 10, 20, 40, 60, 70, and 80% of the sky. These S/Ns have been calculated assuming that there is 10% residual dust in the CIB maps. No signal with a good S/N is detected for the ISW effect in these cases. The best-case scenario seems to be for the 353 GHz frequency over 20% sky, where the S/N reaches 1.51.
