Log of the VLTI/GRAVITY observations of NGC 3783 used in this work.
| Date | On-source | Seeing | Coherence |
|---|---|---|---|
| time (min) | (″) | time (ms) | |
| 2018 Jan. 07 (*) | 80 | 0.38−0.70 | 5.7−10.3 |
| 2018 Jan. 08 (*) | 30 | 0.47−0.58 | 7.8−10.6 |
| 2018 May 31 (*) | 95 | 0.38−0.64 | 2.5−5.3 |
| 2019 Feb. 16 (†) | 140 | 0.45−0.94 | 5.2−13.8 |
| 2019 Mar. 31 (*) | 85 | 0.40−0.67 | 3.0−4.9 |
| 2020 Mar. 08 (†) | 55 | 0.35−0.78 | 4.6−10.0 |
Notes. On-source time in Col. 2 reports only the frames for which the fringe tracking ratio was > 80%. The seeing and coherence times are based on the measurements of the Differential Image Motion Monitor and Multi-aperture Scintillation Sensor on Paranal. (*)K stars were observed as calibrators. (†)B stars were observed as calibrators.
