Table 2
Dependence of the significance of the signal (S = signal/error) on total number counts (net counts within r500) for P3/P0c and wc.
| P3/P0c | Total count number | S = 1 | S = 3 |
|
|
|||
| 1000 | 3.0 × 10-7 | 3.4 × 10-6 | |
| 2000 | 1.4 × 10-7 | 1.6 × 10-6 | |
| 30 000 | 4.5 × 10-9 | 6.0 × 10-8 | |
|
|

| w c | Total count number | S = 1 | S = 3 |
|
|
|||
| 200 | 2.4 × 10-3 | 2.0 × 10-2 | |
| 500 | 1.4 × 10-3 | 1.0 × 10-2 | |
| 1000 | 9.0 × 10-4 | 6.0 × 10-4 | |
| 30 000 | 1.6 × 10-4 | 8.0 × 10-4 | |
Notes. We call values with S > 3 significant signals, however for low counts observations a less conservative value like S = 1 has to be used.
