Sky image of the Geminga pulsar region in the 4−12 keV obtained with ART-XC, shown in units of counts pix−1. The image is smoothed with the dmimgadapt task from CIAO-4.15 using a Gaussian kernel. The corresponding exposure map is highly uniform, with ∼1800 seconds per pixel. The position of the Geminga pulsar is marked by a white circle of 1° diameter. The grid is displayed in Galactic coordinates. The green circle denotes the ART-XC FOV, 36′ in diameter.
