Description

This data collection contains pre-processed data from the NenuFAR Key Project 07 observations of Jupiter used in Louis et al. (2025).

The data files are provided in hdf5 format. Each file contains:

1. a Time array (format: unix, units: s) that contains the Epoch information (see below for the coverage). The data have been rebinned to a time resolution of 600 seconds.
2. a Frequency_Obs array (units: MHz that contains the Frequency of the observation. The data have been rebinned to a frequency resolution of either 1 or 5 MHz.
3. a Dataset 2D array containing the data for each Epoch and frequency step.
4. a Stokes variable that indicates the Stokes parameters in Dataset.
5. a key_project variable that indicates this data were acquired for the Key Project 07 (Jupiter).
6. a Target variable that indicates the target of the observation (Jupiter).
7. T_star indicates here the periodicity of Jupiter (units: hours).
8. T_exoplanet indicates here the periodicity of the Galilean Moon Io (units: hours).

How to use

The data files can be read using the Louis et al. (2025b) pipeline:

from lomb_scargle_calculation import read_hdf5_file
filename = <filename.hdf5>
(time_datetime_beam_ON_VI,
            frequencies_beam_ON_VI,
            data_final_beam_ON_VI,
            stokes_beam_ON_VI,
            key_project_beam_ON_VI,
            target_beam_ON_VI,
            T_exoplanet_beam_ON_VI,
            T_star_beam_ON_VI
            ) = read_hdf5_file(filename, dataset=True, LS_dataset = False)
