Table 2.
Number of transits required to reach 50 ppm min−1 noise level with CHEOPS and PLATO for different stellar magnitudes.
| CHEOPS |
PLATO |
||||
|---|---|---|---|---|---|
| mV | Noise/min | # transits | mV | Noise/min | # transits |
| 6.5 | 150 ppm | 9 | 8 | 62 ppm | 2 |
| 8 | 186 ppm | 14 | 10 | 209 ppm | 17 |
| 10 | 319 ppm | 40 | 11 | 263 ppm | 28 |
| 12 | 855 ppm | 293 | 13 | 619 ppm | 153 |
Notes.
Noise levels of CHEOPS were obtained from CHEOPS science team (priv. comm.) and that for PLATO was converted to ppm min−1 from Rauer et al. 2014 (Table 2 and Fig. 14).
