Content description based on the data set catalog file description for the PDS3 version, EAR-A-I0688-5-CMORMETORB-V2.0
======================================================================================================================

Note: for PDS3 data sets migrated to PDS4, the following text is taken
verbatim from the data set description and confidence level note of the
PDS3 data set catalog file. In these cases, some details may not be correct
as a description of the PDS4 bundle.
                                                           
    The Canadian Meteor Orbit Radar, (CMOR), located near Tavistock, Ontario  
    and operated by the University of Western Ontario, initially carried out a
    survey of meteor showers over the period 2002-2006, the results of which  
    were published in Brown et al. (2008) and which were archived in PDS in   
    version 1.0 of this data set.  The survey was subsequently extended       
    through 2008, and the extended results published in Brown et al. (2010).  
    In the following description, Survey I refers to the initial 2002-2006    
    reconnaissance survey, and Survey II refers to the combined data from the 
    full 2002-2008 survey.  This version (2.0) of the data set contains the   
    full results from Survey II.                                              
                                                                              
    A total of just over 3 million meteoroids were detected in survey II, and 
    their orbits determined.  From these data, an automated stream search     
    algorithm identified 117 meteor showers, including 42 of the 45 streams   
    previously identified in survey I.  Removing possible duplicate showers   
    from the results leaves a total of 109 distinct meteor showers.  This data
    set presents the orbital parameters measured for the 117 major and minor  
    meteor streams which were detected during survey II.  Tables showing      
    linkages between the streams, possible parent bodies, and grouping of the 
    streams into complexes are also included.

    radiants.tab - Contains information about the radiants of the 117 detected
    showers, including the time of maximum, duration, geocentric radiant      
    coordinates, and velocity at time of maximum, as well as radiant drift and
    associated error.  Reproduces the content of Table 1 of the paper.        
                                                                              
    orbits.tab - Contains information about the shower mean orbits, computed  
    using the radiant and velocity observed at shower maximum.  Included are  
    orbital elements and the number of orbits used to compute the mean stream 
    orbit.  Reproduces the content of Table 2 of the paper.                   
                                                                              
    complexes.tab - Groups the detected streams into seven major stream       
    complexes.  Reproduces the content of Table 3 of the paper.               
                                                                              
    linkages.tab - Lists possible interstream linkages, along with possible   
    parent bodies.  Reproduces the content of Table 4 of the paper.
