XMM-Newton observations of HD 149404.
| Obs. | Obs. ID. | Duration (ks) | JD-2458 000 | φ | Orbital config. | CR (ct s−1) |
|---|---|---|---|---|---|---|
| 1 | 0820510401 | 24.4 | 346.737 − 347.089 | 0.209 − 0.244 | Quadrature | 0.315 ± 0.004 |
| 2 | 0820510501 | 26.0 | 354.222 − 354.632 | 0.971 − 0.013 | ON9.7I star in front | 0.233 ± 0.003 |
| 3 | 0820510601 | 21.5 | 359.125 − 359.437 | 0.471 − 0.502 | O7.5I(f) star in front | 0.339 ± 0.004 |
Notes. The duration indicated in the third column corresponds to the effective exposure time of the EPIC-pn camera (i.e. after removing the time interval affected by a flare in the second observation). The orbital phase range quoted in the fifth column was computed using the photometric ephemeris of Rauw et al. (2019): HJD(φ = 0) = 2 457 215.9943 + (9.81475 ± 0.00084) E. The count rate in the last column corresponds to the net (i.e. background-corrected) value recorded with the EPIC-pn camera within the spectral extraction region over its full energy band.
