ORN NDA NewRoutine Jupiter EDR FITS data collection data collection

Monday 13 March 2023, by Baptiste Cecconi

This data collection is composed of daily decametric observations of Jupiter acquired by the Nançay Decameter Array (NDA) with its NewRoutine receiver at the Observatoire Radioastronomique de Nançay (ORN) in Nançay, France.

Link to data


Decametric radio observation from Nançay Decameter Array (NDA) (Lamy et al. 2017). The NDA at the Observatoire Radioastronomique de Nancay (ORN) is a phased array of 144 "Teepee" helicoidal antenna, half of which being Right Handed (RH) polarized and the other half being Left Handed (LH) polarized. Four receivers are currently connected to the NDA, sampling data in spectral ranges within 5 to 80 MHz. This collection covers the NewRoutine high resolution receiver.


Data format

The NewRoutine data files are distributed in FITS format.

Directory and file naming convention

The directory structure is built with yearly and monthly subdirectories.
