Notes. Column description: Burst: name of the event (YYMMDD); ScW: pointing ID in which the event occurred; UT: trigger time; T90: duration of the event; Fluence: fluence in units of counts, referring to the T90 interval and to the energy interval given in column 7; Peak Flux: in units of count/s in the same time and energy intervals as for fluence; Instrument: telescopes/instruments that observed the event (A = AGILE, B= Swift/BAT, F = Fermi/GBM, II = INTEGRAL/ISGRI, IA = INTEGRAL/SPI-ACS, K= Wind/Konus, R = RHESSI, S = Suzaku/WAM). (a) = T90 refers to the 260–312 keV range, that gives a better signal to noise ratio. (b) = The bright GRB 060901, detected by INTEGRAL over  ~20 s, saturated ISGRI telemetry but did not affect PICsIT data. In PICsIT light curve the burst shows a multipeak structure extending over 8 s, in accordance with Konus main event (followed, in Konus data, by a faint tail up to 15 s). (c) = GRB 060928 is structured in two main episodes at 01:17:05 and 01:17:20, with duration  ~14 s and  ~25 s, respectively. PICsIT observed both events (Fig. 13) but our analysis has been restricted to the main second event (Fig. 14). (d) = A linear fit of the background was required for T90 computation. (e) = PICsIT light curves are severely affected by data gaps at all energies (Fig. 16). A T90 of 11 s was obtained by McGlynn et al. (2009) with SPI. (f) = For T90 computation the background was fitted to a polynomial function of the third degree. (g) = For T90 computation the background was fitted to a polynomial function of the second degree.

Notes. (h) = We analyzed the main pulse of the event, which is composed of three peaks over  ~70 s. (i) = The burst was observed by PICsIT in two main episodes separated by 50 s and extending over 120 s. The first smaller peak seems to be affected by count drops and therefore the analysis was conducted on the second event only. (j) = The bright GRB 080723B fell in the ISGRI FoV, with an off-axis angle Θ ~ 8°, and saturated the available telemetry. PICsIT data show gaps at all energies that are limited to few time bins, however, and did not affect the T90 computation. We report the lower limits of the peak flux and fluence. (k) = in PICsIT data the burst occurs  ~60 s after the Swift/BAT trigger and coincides with the brightest portion of this long event (~130 s).
