Sensitivity maps within the INTEGRAL IBIS/ISGRI (20–200 keV), IBIS/PICsIT (260–2000 keV), SPI (25–8000 keV), and the combined JEM-X1 and JEM-X2 modules (3.–35. keV) FoVs during the time interval spanning from a minimum of T₀−30 s to a maximum of T₀ + 287 s (depending on instrument). The units reported below the color bar are erg cm^-2 s^-1. We also show in green the 90% and 50% confidence level contours of the LIGO LVT151012 localization region.
