Relative flux map of the region observed with the MAGIC telescopes. The modeled sources MAGICJ1857.2+0263, MAGIC J1857.6+0297, and HESS J1858+020 are marked with white diamonds. The center of W44 is marked with a green cross. We also show the location of HESS J1857+026 from Abdalla et al. (2018) with a dark blue triangle. The NW center position is marked with a yellow star, and the extension is indicated by the yellow circle. The 39% and 68% containment contours of the MAGIC PSF are depicted in the bottom left corner.
