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.

Description (abstract):
    X-ray fluxes or upper limits in the 2-10 keV energy band from the HEAO
    1 A-2 experiment are  given for  well-defined samples  of QSOs  and of
    Seyfert galaxies of  types 1,  1.5 and  2, and  for a  list of  BL Lac
    objects (334  sources in  total). All  on-orbit X-ray  measurements of
    these objects  published between 1976 and  1986 from other experiments
    have also been catalogued.

If one single energy value is reported, the measurement is monochromatic at that energy. For some EXOSAT Low-Energy Experiment measurements, only filters are reported in column Instr. The relative spectral windows are still poorly defined and may undergo revisions hence are not reported in this column Note (4): If for a given measurement more than one code are quoted, the first code refers to the original paper from which the measurement quoted in table2 is taken. The following code(s) refer to paper(s) where the same measurement is quoted and discussed. Such references are reported here in order to provide more complete information. While special care was devoted to finding original measurements, no completeness is claimed on subsequent publications dealing with the same measurement.
Individual note: For NGC 4151 (table3): reported in reference 15 there are also the fluxes of NGC 4151 obtained interpolating the counts with different spectra. Measurements around 100 Kev for NGC 4151 have been collected in reference 80 Byte-by-byte Description of file: table6 table7 table8 table9
