ADCADC/CDS Standard Document for Catalog:
/external/nonstell/E7002/

The ADC has expanded its resources in order to better serve our users, we have developed a new category called "external" to complement our catalogs and journal table directories. You can access the data set described here through the URL:
http://gammaray.msfc.nasa.gov/batse/.

The following is an abbreviated "ReadMe" document that describes this external data set.

Brief Description:
    The BATSE burst team is pursuing a policy of making data available to 
    the scientific community as soon as possible. In regard to burst catalog
    data, this means making the various catalog tables public as they are 
    generated and before they are published as an official catalog. Some of 
    these data, locations for example, are close to current, while others 
    will take a little longer. The data available now are: burst times and 
    locations, peak fluxes and fluences, and the trigger criteria. The 
    gamma-ray burst positions are plotted on the BATSE Gamma-Ray Burst 
    Skymap. 

    We hope to keep these tables current to within a week or two. We will 
    be adding, as they become available, the following data: the sky 
    exposure versus declination, T50 and T90 durations, Cmax/Cmin, trigger 
    efficiency versus peak flux, and comments. 

    Triggers 105 through 5586, which are gamma-ray bursts up to 29 August, 
    1996, are published as the BATSE 4B Catalog. This catalog contains 1637 
    gamma-ray bursts. Subsequent data should be considered preliminary and 
    subject to change. 

    In analyzing these data, it is important to note that the trigger 
    criteria, including the energy range, have been changed quite often since 
    the end of the 3B catalog. This information is contained in the Trigger 
    Criteria Table. 

    The BATSE trigger numbers correlate all the tables of the catalog. The 
    trigger number is a running sequence of BATSE triggers which include 
    cosmic bursts, solar flares and other events. The sequence begins with 
    trigger 105. The Basic Information Table contains all of the gamma-ray 
    burst triggers, while the remaining tables contain subsets of these 
    triggers.
