From precursor to afterglow: The complex evolution of GRB 210312B

Open Access

Fig. 5.

Detection of the burst by INTEGRAL during the primary pulse (a) and precursor (b) phases. Shown are S/N maps of the sky region $1 \binom{°}{\cdot} 5 \times 1 \binom{°}{\cdot} 5$ $1{\circ \atop \cdot } 5\times 1{\circ \atop \cdot } 5$ in size centered on the GRB 210312B position. They were obtained by IBIS/ISGRI in the 20–100 keV range (left; solid lines show the S/N levels at 2, 3, 4, … σ) and JEM-X in the 3–20 keV range (right; the S/N levels are at 1, 2, 3, … σ). The dashed lines show a grid of Galactic coordinates. The burst was detected with IBIS/ISGRI at 19.1σ during the primary peak and 6.6σ during the precursor, and with JEM-X at 5.2 and 4.3σ, correspondingly.
