VizieR Online Data Catalog: List of isolated emission episodes in GRB (Charisi+, 2015)

We analysed GRB light curves from the three main GRB catalogues: (i) the Gamma-ray Burst Monitor (GBM) on board Fermi Gamma-ray Space Telescope (Meegan et al., 2009ApJ...702..791M), (ii) the Burst Alert Telescope (BAT) on the Swift satellite (Gehrels et al., 2004ApJ...611.1005G), and (iii) the BATSE on board Compton Gamma-Ray Observatory (Fishman et al., 1989, Its Max'91 Workshop 2: Developments in Observations and Theory for Solar Cycle 22. Wingle R. M., Dennis B. R., editors. 1989. p. 96.). We analysed GRBs detected prior to 2014 January 01. The search was confined to long GRBs with nominal duration T90 (T₉₀>2s), where T90 is defined as the time interval during which 90% of the GRB fluence was detected with 5% fluence detected both before and after the interval. Note that T90 was the only property considered in identifying long GRBs. The main reason for this selection is the reduced accuracy of the search for variability shorter than the bin size of the available light curves.

Fermi-GBM consists of 12 NaI detectors, sensitive to energies from 8keV to ~1MeV, which cover the entire unocculted sky, along with two BGO detectors sensitive to higher energy photons (~200keV to ~40MeV). The GBM burst catalogue (http://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html) consists of 1276 GRBs (2008 July-2013 December) and the data are publicly available (http://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/)

Swift-BAT is a sensitive gamma-ray detector with a wide field of view (1.4sr) designed to provide GRB triggers with accurate localization. During the considered observation period up to the end of 2013 (2004 Decembe-2013 December), Swift had detected 833 GRBs (Sakamoto et al., 2011ApJS..195....2S, Cat. J/ApJS/195/2). The data are retrieved from the public archive (http://swift.gsfc.nasa.gov/archive/)

BATSE consisted of eight large NaI area detectors (LADs) covering the energy range of ~25keV to ~2MeV, and was able to observe the entire unobstructed sky. Over its nine years of operation (1991 April-2000 May), it detected 2702 GRBs (http://gammaray.msfc.nasa.gov/batse/grb/catalog/current/).

For each burst, the daily LAD discriminator data (DISCLA) are retrieved from the archive (ftp://legacy.gsfc.nasa.gov/compton/data/batse/daily)
