INTRODUCTION

=============================================================================

 

    This dataset contains processed radio science data and results of the

Juno Ganymede radio occultation. This dataset is provided in order to 

supplement the submitted article to the "Geophysical Research Letters"

journal:

 

    Buccino, D.R., et al (2024), Electron Density in Io’s Alfvén Wing 

    Observed via Radio Occultation with Juno, Geophysical Research 

    Letters, submitted July 2024.

FILE FORMAT

=============================================================================

 

    This dataset contains only ASCII formatted files. There are two formats,

    a plain-text file with the extension *.txt and a comma-separated file

    with the extension *.csv.

 

 

    PLAIN-TEXT FILES

    -------------------------------------------------------------------------

 

    The plain ASCII text files (TXT) files are fixed-width columns. Values in

    each data file are separated with spaces. Each column is defined 

    by a header row which provides a description of each column.

 

    CSV FILES

    -------------------------------------------------------------------------

 

    The Comma-Separated Value (CSV) files are plain-text files. Values in

    each data file are separated using a comma ",". Each column is defined 

    by a header row which provides a description of each column.
