Abstract:
We present Interplanetary Network (IPN) data for the gamma-ray bursts
in the first Fermi Gamma-Ray Burst Monitor (GBM) catalog. Of the 491
bursts in that catalog, covering 2008 July 12 to 2010 July 11, 427
were observed by at least one other instrument in the nine-spacecraft
IPN. Of the 427, the localizations of 149 could be improved by arrival
time analysis (or "triangulation"). For any given burst observed by
the GBM and one other distant spacecraft, triangulation gives an
annulus of possible arrival directions whose half-width varies between
about 0.4' and 32°, depending on the intensity, time history, and
arrival direction of the burst, as well as the distance between the
spacecraft. We find that the IPN localizations intersect the 1σ
GBM error circles in only 52% of the cases, if no systematic
uncertainty is assumed for the latter. If a 6° systematic
uncertainty is assumed and added in quadrature, the two localization
samples agree about 87% of the time, as would be expected. If we then
multiply the resulting error radii by a factor of three, the two
samples agree in slightly over 98% of the cases, providing a good
estimate of the GBM 3σ error radius. The IPN 3σ error
boxes have areas between about 1 arcmin2 and 110 deg2, and are, on
the average, a factor of 180 smaller than the corresponding GBM
localizations. We identify two bursts in the IPN/GBM sample that did
not appear in the GBM catalog. In one case, the GBM triggered on a
terrestrial gamma flash, and in the other, its origin was given as
"uncertain." We also discuss the sensitivity and calibration of the
IPN.
Description:
This paper presents the latest in a series of catalogs of gamma-ray
burst (GRB) localizations obtained by arrival time analysis, or
"triangulation" between the spacecraft in the third Interplanetary
Network. we present the localization data on 149 bursts which occurred
during the period covered by the first, two-year Fermi Gamma-Ray Burst
Monitor (GBM) GRB catalog (Paciesas et al. 2012, Cat. J/ApJS/199/18;
2008 July 12 to 2010 July 11).
Every cosmic burst detected by the GBM was searched for in the IPN
data; GBM localizations were used to calculate arrival time windows
for Odyssey and MESSENGER, but the total crossing time windows defined
by light-travel times were examined in all cases. The resulting
detections are given in Table 2. Konus and Suzaku can detect bursts in
both triggered (2-64ms time resolution) and an untriggered (1-3s time
resolution) modes; both modes are counted as detections in this table.
Also, detections by several instruments which are not part of the IPN
have been reported in the table, namely the Fermi LAT, Monitor of
All-sky X-ray Image (MAXI), and Rossi X-Ray Timing Explorer (RXTE).
