AGILECAT Catalog
This table contains the first catalog of high-confidence gamma-ray sources
detected by the AGILE satellite during observations performed from July 9,
2007 to June 30, 2008. Cataloged sources were detected by merging all the
available data over the entire time period. AGILE, launched in April 2007,
is an Italian Space Agency (ASI) mission devoted to gamma-ray observations in
the 30 MeV - 50 GeV energy range, with simultaneous X-ray imaging capability
in the 18 - 60 keV band. This catalog is based on Gamma-Ray Imaging Detector
(GRID) data for energies greater than 100 MeV. For the first AGILE catalog,
the authors adopted a conservative analysis, with a high-quality event filter
optimized to select gamma-ray events within the central zone of the instrument
field of view (radius of 40 degrees). This is a significance-limited
(4-sigma) catalog, and it is not a complete flux-limited sample due to the
non-uniform first-year AGILE sky coverage. The catalog includes 47 sources,
21 of which are associated with confirmed or candidate pulsars, 13 with
blazars (7 flat-spectrum radio quasars [FSRQ], 4 BL Lacs, 2 unknown type),
2 with HMXRBs, 2 with SNRs, 1 with a colliding-wind binary system, and 8
with unidentified sources.
AGILEUPVAR Catalog
This table contains some of the results from a variability study of a sample
of bright gamma-ray (30 MeV - 50 GeV) sources. This sample is an extension of
the first AGILE catalog of gamma-ray sources (1AGL), obtained using the
complete set of AGILE observations in pointing mode performed during a 2.3
year period from July 9, 2007 until October 30, 2009. The dataset of AGILE
pointed observations covers a long time interval and its gamma-ray data
archive is useful for monitoring studies of medium-to-high brightness
gamma-ray sources. In the analysis reported here, the authors used data
obtained with an improved event filter that covers a wider field of view, on
a much larger (about 27.5 months) dataset, integrating data on observation
block (OB) time scales, which mostly range from a few days to thirty days.
The data processing resulted in a better characterized source list than 1AGL
was, and includes 54 sources, 7 of which are new high galactic latitude
(|b_II_|>= 5 degrees) sources, 8 are new sources on the galactic plane, and
20 sources are from the previous catalogue with revised positions. Eight 1AGL
sources (2 high-latitude and 6 on the galactic plane) were not detected in
the final processing either because of low OB exposure and/or due to their
position in complex galactic regions. The reference paper reports the results
in a catalog of all the detections obtained in each single OB, including the
variability results for each of these sources. In particular, the authors
found that 12 sources out of 42 or 11 out of 53 are variable, depending on
the variability index used, where 42 and 53 are the number of sources for
which these indices could be calculated. Seven of the 11 variable sources are
blazars, the others are the Crab pulsar+nebula, LS I +61 303, Cyg X-3, and
1AGLR J2021+4030.
This HEASARC table contains 54 AGILE-detected sources and the main parameters
of their maximum significance (defined by sqrt(TS)) detections: for each
source, the name, coordinates, the sqrt(TS) value as a measure of the
detection significance, the E > 100 MeV flux, the four variability indices
described in Section 5 of the reference paper, the number of detections, the
confirmed counterparts and source class, if any, and other possible
associations ordered according to the angular distance from the AGL source
are given. These data are listed in Table 5a of the reference paper. This
HEASARC table does not contain the list of fluxes for these sources as
measured in all of the relevant individual OBs (Table 5b in the reference
paper). This latter is obtainable from the CDS:
