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

    This dataset contains open-loop data collected by the Planetary Radar
and Radio Science Group at the Jet Propulsion Laboratory from the Low-SNR
Ground System Demonstration with DSS-25 in May 2020. Futhermore, it
also provides the necessary data behind the figures in the corresponding
publication. This dataset is provided in order to supplement the submitted
article to the "Radio Science" journal

    Buccino, D.R., et al (2023), Precision of Spacecraft Doppler Tracking 
        at Low Signal-to-Noise Ratios, Radio Science, submitted
        January 2023.

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

    This archive contains several data types, located within subdirectories.
    
    ROOT
     `- 159TEST2022133_1845X25X25RO.A02_XATnn_nndBHz
     
         These files are the open-loop data collected at the DSN 
         during the test. There are six files, one for each SNR level. The
         files are in the DSN-standard 0159-Science format (binary data).
         To decode these files, one should utilize the software 
         interface specification documents from the Planetary Data System
         radio science documentation bundle:

              radiosciencedocs/urn-nasa-pds-radiosci_documentation/
     
     `- figures.zip
     
         This directory contains all data necessary to reproduce the figures
         in the publication. Data include Doppler residuals, SNR measurement,
         Allan deviation and associated parameters. Each file in this 
         directory is plain-text.
