Summary of sensitivities for the different instruments on board INTEGRAL, related to the detection within their FoVs of a GRB afterglow-like event as the counterpart of LVT151012.

Instrument Energy range Field of view Fraction of the LVT151012 Angular resolution 3σ sensitivity
deg2 localization (erg cm-2 s-1)

JEM-X 3–30 keV 110 4 % 3 1.4 × 10-9
ISGRI 20–200 keV 820 19 % 12 7.4 × 10-10
PICsIT 260–2600 keV 820 19 % 30 2.4 × 10-8
SPI 25–1000 keV 790 18 % 2.5° 4.2 × 10-9

Notes. Data were integrated within the time interval spanning from a minimum of T0−30 to a maximum of T0 + 287 (depending on the instrument) and a power-law shaped spectral energy distribution with a photon index of − 2 has been assumed for the event to be detected. The limit of the FoVs has been set to the point where a worsening of the instrument sensitivity by a factor of 20 compared to the on-axis value is reached.
