eROSITA count map of HESS J1702-420 region (in galactic coordinates). Green and magenta ellipses in both panels indicate the positions and TeV sizes of HESS J1702-420A and HESS J1702-420B sources. The right panel shows the region with the bright nearby X-ray sources masked for the searches of the diffuse emission from the X-ray counterpart of the HESS J1702-420 TeV complex. The dashed yellow circle of 3°-radius is centred on the HESS J1702-420A position and illustrates the maximal radius of the ON region used for the searches. The magenta truncated annulus in the right panel illustrates the shape and extent of the corresponding OFF region.
