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.

R15 : R15 Counts
Note (3): spectral window of observation:
The reader is cautioned, however, that the quoted spectral window does
not always match the energy band over which the photons were actually
detected.
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
