Abstract:
We present the catalog of sources detected in 70 months of
observations with the Burst Alert Telescope (BAT) hard X-ray detector
on the Swift gamma-ray burst observatory. The Swift-BAT 70 month
survey has detected 1171 hard X-ray sources (more than twice as many
sources as the previous 22 month survey) in the 14-195 keV band down
to a significance level of 4.8σ, associated with 1210
counterparts. The 70 month Swift-BAT survey is the most sensitive and
uniform hard X-ray all-sky survey and reaches a flux level of
1.03x10-11erg/s/cm2 over 50% of the sky and 1.34x10-11erg/s/cm2
over 90% of the sky. The majority of new sources in the 70 month
survey continue to be active galactic nuclei, with over 700 in the
catalog.
Description:
This paper extends the BAT 22 month paper (Tueller et al. 2010,
Cat. J/ApJS/186/378) to include all sources detected in the first 70
months of data between 2004 December and 2010 September.

Note (1): If a BAT name exists in the 22-month catalog (Tueller et al. 2008,
Cat. J/ApJ/681/113), then that name is used. If there is no 22-month
BAT name, then the BAT name listed here is the name that was used to
request XRT followup observations (and used in the HEASARC archive).
When no previous BAT name for this source exists, we list here a BAT
name derived from the BAT position in this catalog.
Note (2): The BAT source positions listed here are all uniformly generated from
the fit BAT positions of the sources in the 70-month data.
Note (3): The counterpart position is the most accurate position known of the
object in the 'CName' column, and is usually taken from NED or SIMBAD.
If no counterpart is known, the fit BAT position is listed.
Note (4): Extracted from the BAT maps at the position listed for the
counterpart. In units of 10-12ergs/s/cm2.
Note (5): What portion of the BAT flux at the counterpart position is
contributed by other nearby sources. The contamination is given
if >2%; see section 4.4 for details.
Note (6): Computed from a power-law fit to the 8-band BAT data
f(E)∝E-Γ
Note (7): Taken from the online databases NED and SIMBAD or in a few cases from
our own analysis of the optical data. A blank indicates that the
object is Galactic.
Note (8): Computed from the flux and redshift in this table, with units of
log(ergs/s).
Note (9): Counterpart association strength flag (as in table 5) as follow:
--------------------------------------------------------------------------
Flag Number % Meaning
--------------------------------------------------------------------------
(Blank) 1017 84.2 Confirmed with X-ray imaging
1 = 36 3.0 Old association held over from previous catalog
2 = 5 0.4 No good hard X-ray source; soft X-ray source
3 = 4 0.3 No X-ray source; source from another waveband
4 = 133 11.0 Unchecked or unavailable X-ray image; educated guess
5 = 2 0.2 No X-ray source; BAT source on Galactic plane
6 = 10 0.8 No X-ray source; BAT source off plane
7 = 3 0.2 No association
--------------------------------------------------------------------------
Note (10): Source class as follows:
0 = Unknown: sources listed with the type unknown either do not have any
known counterpart, or are associated with sources of unknown physical
type. (65 sources)
1 = Galactic: Sources classified only as "Galactic" are so assigned because
of observed transient behavior in the X-ray band along with insufficient
evidence to place them in another class. (23 sources)
2 = Galaxy: Sources in the "Galaxy" class are seen as extended in optical
or near-IR imagery, but do not have firm evidence (such as an optical
spectrum) from other wavebands confirming whether they harbor an AGN.
(111 sources)
3 = Galaxy Cluster (19 sources)
4 = Seyfert I (Sy1.0-1.5) (292 sources)
5 = Seyfert II (Sy1.7-2.0) (261 sources)
6 = Other AGN (23 sources)
7 = Blazar/BL Lac object (49 sources)
8 = QSO: AGNs with BAT luminosities greater than 1045 erg/s or listed in NED
as radio galaxies are classified as QSO. (86 sources)
9 = Cataclysmic variable star (CV) (55 sources)
10 = Pulsar (20 sources)
11 = Supernova remnant (SNR) (6 sources)
12 = Star (14 sources)
13 = High mass X-ray binary (HMXB) (85 sources)
14 = Low mass X-ray binary (LMXB) (84 sources)
15 = Other X-ray binary (XRB) (17 sources)
