Abstract:
    We compiled a sample of 95 AGNs serendipitously detected in the
    3-20keV band at Galactic latitude |b|>10deg during the RXTE slew
    survey (XSS, Revnivtsev et al., Cat. J/A+A/418/927), and utilize it
    to study the statistical properties of the local population of AGNs,
    including the X-ray luminosity function and absorption distribution.
    We find that among low X-ray luminosity (LX<1043.5erg/s) AGNs, the
    ratio of absorbed (characterized by intrinsic absorption in the range
    1022cm-2<NH<1024cm-2) and unabsorbed (NH<1022cm-2) objects
    is 2:1, while this ratio drops to less than 1:5 for higher luminosity
    AGNs. The summed X-ray output of AGNs with LX>1041erg/s estimated
    here is smaller than the earlier estimated total X-ray volume
    emissivity in the local Universe, suggesting that a comparable X-ray
    flux may be produced together by lower luminosity AGNs, non-active
    galaxies and clusters of galaxies. Finally, we present a sample of 35
    AGN candidates, composed of unidentified XSS sources.

Description:
    Catalog of 95 identified AGNs serendipitously detected at |b|>10deg
    during the RXTE slew survey (XSS, J/A+A/418/927) is presented. Most
    of these AGNs belong to the local population (z<0.1). For each source
    the following information is provided: AGN class, count rate in two
    energy bands 3-8keV and 8-20keV, observed and intrinsic
    (absorption-corrected) luminosity in the 3-20keV band, intrinsic
    absorption column density. Also a catalog of 35 AGN candidates,
    composed of unidentified XSS sources is presented.

Note (1): AGN classification is as follows:
      RQQ: radio-quiet quasar
      RLQ: radio-loud quasar
       BL: blazar (BL Lac object or flat-spectrum radio quasar)
       S1: Seyfert 1 galaxy (types 1, 1.2 and 1.5)
     NLS1: narrow-line Seyfert 1 galaxy
       S2: Seyfert 2 galaxy (types 1.8, 1.9 and 2)
       RG: radio galaxy
     BLRG: broad-line radio galaxy
     NLRG: narrow-line radio galaxy
    LLAGN: low luminosity AGN
Note (2): Distance adopted for 10 nearby sources, in the other cases
    luminosity distance was computed assuming
    (H0,Omegam,Omegalambda)=(75km/s/Mpc, 0.3, 0.7)
Note (3): Limits are 1 sigma if based on XSS hardness ratio and more
     conservative in other cases.

History:
  * 01-Dec-2004: Corrected version of table2 from the author
    (Sergey Sazonov). In particular the source XSS J17276-1359 which
    existed in both table was removed; and one missing source
    XSS J15360-4118 was added.
