INTRODUCTION
=============================================================================

    This dataset contains processed radio science data and results of the
Juno Europa radio occultation. This dataset is provided in order to 
supplement the submitted article to the "Geophysical Research Letters"
journal:

    Parisi, M. et al. (2023 or 2024), Measurements of Europa's Ionosphere from Juno's close flyby, Geophysical Research 
    Letters, submitted September 2023.

Please note the raw data used in this analysis are not provided in this
supplementary dataset. The raw Juno Gravity Science Data may be found at

ARCHIVE INFORMATION
=============================================================================

    This archive contains two files within the root directory.
    
     - JunoE45OccData_Ingress_v1.csv

            This data file contains the INGRESS data relevant to the radio
            occultation. The data is a timeseries of impact parameter, 

           the uncalibrated frequency residuals, the calibrated frequency residuals, 

           Total Electron Content, Electron density, 1-sigma electron density uncertainty (thermal only)  

           and 1-sigma electron density uncertainty (thermal+trajectory).

     - JunoE45OccData_Egress_v1.csv

            This data file contains the EGRESS data relevant to the radio
            occultation. The data is a timeseries of impact parameter, 

           the uncalibrated frequency residuals, the calibrated frequency residuals, 

           Total Electron Content, Electron density, 1-sigma electron density uncertainty (thermal only)  

           and 1-sigma electron density uncertainty (thermal+trajectory).

FILE FORMAT
=============================================================================

    This dataset contains only a comma-separated text files which are
given with the "*.csv" extension.

    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.
