This is a catalog of transients that appear to be gamma ray
bursts. None of the events in this catalog activated the
onboard burst trigger, however, for the reasons described in the Introduction. Each burst has its own page for
browsing by humans. For input into machines, the data
in this catalog are also available in ASCII
format and a binary IDL "save /xdr" format.
The raw DISCLA data (summed in the two detectors most brightly
illuminated by the burst) for each event are available in BFITS format
from the individual burst pages. (To download BFITS files in bulk, go
to the BFITS page.)

This is a catalog of transients that appear to be bursts from Soft
Gamma-ray Repeaters. These events events have durations shorter than
the time resolution of the DISCLA data, significant counts in channels
1 and 2 (25-100 keV) but none in channel 3 (100-300 keV), and they
tend to occur during known outbursts of SGR sources. Of the 25 events
listed here, 24 are consistent with activity from SGR 1806-20. The
one that is not, NTB 941022.58, has an unknown origin. Each burst has
its own page for browsing by humans. For input into machines, the
data in this catalog are also available in ASCII format and a binary IDL "save /xdr" format.

This is a catalog of transients that do not appear to
be gamma ray bursts or bursts form SGRs. These events also do not
show the characteristics of solar flares, atmospheric electron
precipitation events, or bursts from sources such as GRO J1744-28.
The bursts in this category most likely represent a variety of causes,
including bursts from X-ray binaries and spectrally soft GRBs. For
input into machines, the data in this catalog are also available in ASCII format and a binary IDL "save /xdr" format.

This is a list of the BATSE trigger numbers for the GRBs that were
detected both the onboard triggered and by the off-line search. These
numbers can be used as keys to look up the appropriate data from the
BATSE burst catalogs.

This is a collection of gamma ray bursts that did activate the
onboard burst trigger. These events provide a way to compare
the results produced by our analysis techniques with the results
published by the BATSE team in the regular BATSE gamma ray burst
catalogs. Generally the agreement is good, but there are cases where
systematic differences are significant. These cases arise because the
off-line search uses only DISCLA data (1.024 s, 4 energy channels) and
because the off-line search assumes all bursts have a power-law
spectrum.

This is a collection of gamma ray bursts that did activate the
onboard burst trigger but that did not have peak fluxes
listed for them in the BATSE catalog as of 1998 August. To complete
the analysis of the peak flux distribution, we derived peak fluxes for
these bursts just as we did for the strictly nontriggered ones.
