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.
