  • NDA Obs. Database - Nancay Decameter Array observation database

    Dynamic Spectra of the Routine observation of Jupiter with the Nancay Decameter Array. This dataset contains two series of dynamic spectra recorded on each of the Nançay decameter sub-arrays (i.e. on Left Hand and Right Hand Polarization). The receiver is sampling from 10 MHz to 40 MHz with 75 kHz steps on the spectral axis. It records one spectrum every second on each polarization. The list of observation frequencies is provided.
