Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

Abstract:
    We present the results of a complete Einstein imaging proportional
    counter X-ray survey of optically-selected galaxies from the
    Shapley-Ames Catalog (Cat. VII/112), the Uppsala General Catalog
    (Cat. VII/26) and the European Southern Observatory Catalog (Cat.
    VII/115). Well-defined optical criteria are used to select the
    galaxies, and X-ray fluxes are measured at the optically-defined
    positions. The result is a comprehensive list of X-ray detection and
    upper limit measurements for 1018 galaxies. Of these, 827 have either
    independent distance estimates or radial velocities. Associated
    optical, redshift, and distance data have been assembled for these
    galaxies, and their distances come from a combination of directly
    predicted distances and those predicted from the Faber-Burstein Great
    Attractor/Virgocentric infall model. The accuracy of the X-ray fluxes
    has been checked in three different ways; all are consistent with the
    derived X-ray fluxes being of <=0.1 dex accuracy. In particular, there
    is agreement with previously published X-ray fluxes for galaxies in
    common with a 1991 study by Roberts et al. (1991ApJS...75..751R) and a
    1992 study by Fabbiano et al. (1992ApJS...80..531F).The data presented
    here will be used in further studies to characterize the X-ray output
    of galaxies of various morphological types and thus to enable the
    determination of the major sources contributing to the X-ray emission
    from galaxies.

Description:
    The Einstein X-Ray Survey data consist of 3 separate kinds of files
    for each of our three data subsets:
    Tables 5-7: These tables give the basic observed data for the galaxies
    for which the authors were able to obtain X-ray data, both detections
    and upper limits. Included are both observed X-ray data and correlated
    optical data.
    Tables 9-11: These tables list the galaxies that were included in the
    search of the IPC images, but for which X-ray fluxes were not
    measured. A code explains why no measurement was made.
    Tables 12-14: These tables list the distance-dependent parameters,
    including predicted distance, method of predicted distance, X-ray
    luminosities or upper limits, absolute B optical diameters and
    absolute B magnitudes.
