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

    This dataset contains high rate data collected by the Advanced Water
Vapor Radiometer (AWVR) at the Deep Space Network's Goldstone Complex in 
California. This dataset is provided in order to supplement the submitted
article to the "Radio Science" journal

    Buccino, D.R., et al (2021), Performance of Earth Troposphere 
    Calibration Measurements with the Advanced Water Vapor Radiometer 
    for the Juno Gravity Science Investigation, Radio Science, submitted
    October 2021.

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

    This archive contains several data types, located within subdirectories.
    
    ROOT
     `- PJ03/
     
         This directory contains all PJ-03 related data, including
         path delay, path delay rate, calibration values, and frequency
         residuals.
     
     `- PJ06/
     
         This directory contains all PJ-06 related data, including
         path delay, path delay rate, and calibration values.
     
     `- PJ08/
     
         This directory contains all PJ-08 related data, including
         path delay, path delay rate, and calibration values.
     
     `- ADEV/
     
         This directory contains troposphere scintillation Allan deviations
         from each perijove. Files are named using the start time of the file,
         in YYYYMMDDHHMM format, where YYYY is the year, MM is the month,
         DD is the day of month, HH is the hour, and MM is the minute.
     
     `- STATS/
     
         This directory contains the Juno perijove frequency residual 
         statistics. Only one file is present in this directory.

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

    This dataset contains two separate file formats as described below.
ASCII plain-text files are given with the "*.txt" extension and the
comma-separated text files are given with the "*.csv" extension.

    TXT FILES
    -------------------------------------------------------------------------

    The ASCII plain-text files are human-readable, space-delimited
    text files. Each column is defined by a header row which provides
    a description of each column. Additional comments may be optionally
    specified by starting a row with the character "#".

    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.

=============================================================================
FIGURE REPRODUCTION
=============================================================================

    This section will describe the data that are used to produce the figures
in the article that describes this dataset.

    FIGURE 1
    -------------------------------------------------------------------------

    Figure 1 is a photograph and is not included in this dataset.

    FIGURE 2
    -------------------------------------------------------------------------

    Figure 2 is produced using files within the "PJ03", "PJ06", and "PJ08"
    directories.
    
    The first row of subfigures are produced by plotting the final three 
    columns of "pjXX_bt_zenith.txt" as a function of time.
    
    The second row of subfigures are produced by plotting the path delay
    componets as a function of time from the "pjXX_pd_awvr.txt" and 
    "pjXX_pd_tsac.txt" data files.

    FIGURE 3
    -------------------------------------------------------------------------

    Figure 3 is produced using files within the "PJ03", "PJ06", and "PJ08"
    directories.
    
    The first row of subfigures are produced by plotting the last column
    of "pjXX_freq_awvr.txt" and "pjXX_freq_tsac.txt".
    
    The second row of subfigures are produced by differencing the values.
    
    FIGURE 4
    -------------------------------------------------------------------------

    Figure 4 is produced using files within the "ADEV" directory.
    
    Each individual file within the "ADEV" directory contains the Allan 
    deviation. Each Allan deviation is plotted on a log-log scale and is
    color-mapped to the calendar date. The file naming convention gives
    the calendar date of data collection, with the filenames starting with
    YYYYMMDD, where YYYY is 4-digit year, MM is 2-digit month, and DD is
    2-digit day of month in UTC time.

    FIGURE 5
    -------------------------------------------------------------------------

    Figure 5 is produced using files within the "PJ03" directory. The
    frequency residual from the "pj03_resid_awvr.csv" and
    "pj03_resid_tsac.csv" is simply plotted as a function of time.
    
    FIGURE 6
    -------------------------------------------------------------------------

    Figure 6 is produced using files within the "STATS" directory. This 
    directory contains a single file, "AWVR_stats_jul2021_v3.csv" and
    contains the root-mean-square of the frequency residuals from Juno 
    perijove passes. The root-mean-square of the frequency residuals
    are plotted using a bar plot and the percent improvement is plotted 
    with a scatterplot.
