Ross 548: frequencies, periods, and amplitudes determined from the new, 20 s cadence mode TESS observations.
| Frequency [μHz] | Period [s] | Ampl. [mma] | TESS pred. ampl. 825 nm [mma] | Weighted mean ampl. [mma] | |
|---|---|---|---|---|---|
| f1 | 4691.908(10) | 213.1329 | 3.98(24) | 4.34 | 6.86(4) |
| f2 | 4699.977(00) | 212.7670 | 2.39(15) | 2.71 | 4.28(4) |
| f3 | 3646.315(16) | 274.2495 | 2.56(22) | 2.79 | 4.41(4) |
| f4 | 3639.328(17) | 274.7760 | 2.18(22) | 2.01 | 3.17(4) |
Notes. For comparison, we also list the predicted amplitudes in the TESS band pass, and finally the weighted mean amplitudes from ground-based measurements.
