Table 1
Observational parameters for the NenuFAR campaign targeting HD 189733.
| Parameter | Value | Units |
|---|---|---|
| Array configuration | Core + Remote MAs | |
| Frequency range | 15.8–62.5 | MHz |
| Frequency resolution a | 15 | kHz |
| Temporal resolution | 8 | seconds |
| Field of view (FoV) b | 20 | degrees |
| Spatial resolution c | 0.5 | degrees |
Notes. (a) The frequency and temporal resolutions listed here correspond to the Level 1 data products, obtained after initial preprocessing steps that involve averaging, and thus differ from the raw data resolution. (b) The FoV is calculated as the full width at half maximum of the angular resolution corresponding to a single MA of NenuFAR at 39 MHz. (c) The spatial resolution is derived at 39 MHz. It is lower than the theoretical resolution of NenuFAR (0.1 degree) at the frequency, due to two of the four remote MAs being flagged during most of the observational campaign.
